2 Factor Authentication (2FA) adds an additional layer of security to your ProtonMail account by adding an additional verification to the login process to protect your account. Currently, ProtonMail supports the OTP protocol, so accounts with 2FA enabled will be prompted to enter a 6-digit code upon logging in. This 6-digit code will be generated by an app that is installed on your mobile phone.
This means that even if your password is somehow stolen, an attacker still cannot get into your account without also having access to your mobile phone. Because of this security benefit, we recommend enabling 2FA on your account.
In order to use 2FA you must have access to a second device with an authenticator application installed, through which you will receive verification codes to authenticate your login. Below you will find some different Authenticator application options. You must install one of these apps first on your mobile phone before you can use 2FA.
Android
iOS
Setting up Two Factor Authentication in ProtonMail
1. Visit the Security tab within the Settings of your account. This can only be done through the web version of ProtonMail found at mail.protonmail.com
2. Select Enable Two-Factor Authentication
3. Open the authenticator app you have chosen on your mobile device and select the option to scan a QR code, or manually enter the authentication key. To scan the code, point your devices camera at the QR code seen in the setting of your ProtonMail account. (Note: the image below is a demo, do not scan it. Scan the image shown in your account.)
4. You will see the following modal that requires you to enter the Login password of your account, along with the two-factor passcode which you will see in the authenticator application you are using.
5. ProtonMail will also provide you with several one-time use recovery codes. Please save these codes in a secure place and do NOT lose them. If you ever misplace or lose your authentication device (mobile phone, etc) these codes will be the only way to log into your account. If you ever lose your second factor device, you can enter these codes instead of the 6-digit authenticator code. Note, each code can only be used once, and they must be used in the listed order, so please save all the codes.
How to authenticate from multiple devices
If you wish to receive you six-digit authentication codes on multiple devices — say, your phone and your tablet — you must have an authentication app installed on each device. Then follow the steps below:
- If you have already enabled two-factor authentication you will need to disable it.
- Then navigate to Settings -> Security and click on “Enable two-factor authentication”.
- Scan the QR code using the authenticator app on each device. You can also make a screenshot of the QR code and save it for later to scan with your other devices.
Or, instead of scanning the QR code, the other option is to click on the “Enter key manually instead” button.
You will be provided with a key that you will need to enter manually in the 2FA app.
For example, below are some screenshots showing how to enter the key manually using Google Authenticator:
If the 2FA is not working, please check the following article for the most common 2FA login problems.
Optional: Switch to Single Password Mode (for Legacy users)
As of version 3.6.0, ProtonMail has switched to supporting a single password mode and this is the new default mode for newly created accounts. The single password mode combines the legacy Login and Mailbox password into a single password without compromising security or privacy. Existing users have the option to stay in two password mode, or switch to single password mode. For users that find having to enter a Login Password, 2FA code, and Mailbox password to access email too cumbersome, we recommend switching to Single Password mode to reduce the number of password prompts by one.

Would vote for the option of two-factor authentication, assuming a correct interpretation of what differing factors of authentication are. There are currently three main “factors” to consider; what you know (username and password), what you are (biometrics) and what you have (cell phone, dongle, etc.). Personally I prefer a combo of what I know and what I have. A simple multi-digit code sent to my cell at the moment of login attempt as an addition to my username and password is the easiest to implement and virtually makes it impossible to hack.
0
YubiKey, OTP (one-time passwords) or similar support would be great besides the general useranme-password. How about username-password to login and YubiKey to Decrypt the messages.

Would like to see two factor authentication but without a cell phone. A cell phone ties a real identity to the account. Security questions can be guessed if enough time is spent following an individual.
I suppose, though, two factor wouldn’t be required if no one knew the email existed.

I would prefer to have two factor without a cell phone as well. Not everyone can afford a cell phone, home phone and internet as well. I really like to have the secret questions and answers and preferably the choice to create your OWN questions and answers, not the standard ones.

I think two factor authentication is mandatory in our modern world of IT vulnerabilities and malware/botnet infestations.
YubiKey would be awesome.
ProtonMail would easily be the most secure email service on the planet with 2 factor authentication.
But now, end users are a keylogged-connection away from having their emails compromised, which is unfortunate. (These days, I honestly believe that two-factor authentication for one’s primary email account is absolutely mandatory, you’d have to be crazy not to have it).
Just one guy’s $.02.

The sooner the better guys, that DDoS attack shows you are a major target. I would feel even more comfortable when you have Two Factor. I’m starting to switch all my accounts that have Two Factor over after getting my bank account hacked (they literally signed in from Nigeria) twice, which I believe was because of LastPass’s security failure.

Yeah, two factor authentication is a great security feature to have. Please add it soon

People who suggest Google Authenticator are simply misinformed. You add no security if you log into your app with Google Authenticator as your 2 Factor because they are on the same phone. If you want to use TOTP then using the Yubikey Authenticator is an option. However this can not be enforced and is a horrible idea.
Hardware based Token over NFC are by far the best option for 2 Factor on Smartphone apps. Lastpass (Password Manager) support this and it works fantastically. They use HOTP and the Yubicloud, a more modern approche would be to use U2F over NFC.
tl;dr: The most secure would definitely be U2F over NFC.

I love this service already even though I haven’t used it yet, but not having two factor authentication would definitely be a big drawback for me.

Google Authenticator or Authy please

Yubikey is the way to go here.
The current setup (one password logs in, the other decrypts) does nothing to protect one token from the vulnerabilities of the other. For example, a keylogger could capture both passwords if they are typed.
Yubikey solves this problem.
However, it’s not true that Yubikey is “virtually unhackable” as someone claimed above. Have a look at the recently disclosed “LostPass” vulnerability. This is essentially a phishing attack in which a login screen that looks pixel-for-pixel identical to the real thing, asks the user for authentication. Password and Yubikey tokens are captured. The attacker then uses these to authenticate himself and gain entry to LastPass.
Nevertheless, Yubikey is far more secure than almost all other 2FA alternatives. For example, NFC Yubikey-enabled logins bypass the problem of logging in through a phone app when its the same phone that would receive Google Authenticator or Authy codes.
Finally, someone above said that Yubikey could not be enforced.
That’s true. But you can’t enforce people using sensible, long and complicated passwords. Or checking their computer for vulnerabilities, rootkits, viruses and a whole lot else besides.
You can’t force everyone to use 2FA, or Yubikey specifically. But that doesn’t mean it shouldn’t be an option. It should.

Still can’t Vote for this but YubiKey.
I can’t and won’t use ProtonMail as my default email provider unless it offers two-factor authentication.

Two-factor implementation is imperative. Basing authentication in passwords is shown to be so weak as to use only the identification.
Passwords are dead.
No use having the entire system encrypted mail if you can access with a simple password.
People use weak password. And the computers is far superior to these. Also social engineering.
A double factor based on something that you have, as a mobile phone, for most people is really simple. There are many applications that generate a seed. SMS sending is not necessary.
It is also interesting to evaluate the direct use of the second factor as the only factor, because if this is used for recovery of the password, the password is not need, except for the convenience of access only with password to an already verified and saved device.
In any case, today a service like this should implement double factor if want to be safe. Meanwhile, this is serious failure for choose this service of mail as the main day to day or for use in actual need for privacy.

Two Factor Authentication is a MUST this days, this times … nowadays every serious company that desire to keeps data and wants to keep their users safely have it, and it’s not a must because every companies have it, but because PROTONMAIL without Two Factor Authentication it’s a incomplete solution!

It’s been 1 year.
Yes the response from 1 day ago indicates it is still in the works, but for all us paid investors this is a huge pain point and quite simply unacceptable if ProtonMail wishes to be at the forefront of email security. YubiKey, Toopher, GoogleAuth, etc. needs to be implemented ASAP. It should be the top priority of any security conscious company.
If a hack occurs against ProtonMail due to not having this feature implemented, ProtonMail would likely see a large exodus in funding and accounts.

Given the security and privacy that is core to the Proton Mail mission, I’m surprised that two factor authentication wasn’t part of the MVP. Authy is an open source client that works on multiple platforms that could manage the client side work. Please consider this a bold double handed vote for 2 factor authentication. This article at Wired is four years old. The TL;DR is that the security flaws in Apple and Amazon’s process would have been mitigated had the author simply had 2 factor authentication implemented on his gmail account: https://www.wired.com/2012/08/apple-amazon-mat-honan-hacking/

You can use it with two password mode. We don’t support SMS, but you can install a 2FA app on your desktop.

This is a good step in the right direction, but OTP is less secure than U2F, which is what larger tech companies are beginning use (at least for employees). Please do not neglect this important, open, and widely used and supported 2FA standard.

As Protonmail does not support yet Yubikey I use as 2nd Auth Factor Yubico Authenticator, that is the same as Google Auth but need the yubikey to generate codes.
The problem is that I use multiple keys, for example one in the desktop and another for mobile.
Aditionally both keys work as a backup or altenative method in case of loss.
As far as I see Protonmail only allows one method for 2nd Factor Auth. Why not allowing more than one method?
0
We plan on supporting more 2FA methods in the future, but we do not have a timeline at the moment.
0
So if Protonmail supports OTP then it would support Yubikey right?
0
I think what would be REALLY NICE too, is a similar article for the other end of the process, which is “how to migrate 2FA to a new device (be it a phone or tablet)”. Good thing you provided those one-time use codes, or that would have been it. And I had to use two codes, one to log in, then one to deactivate 2FA. From there all was good to reactivate it. Now that it’s fresh in my head, I will probably remember… in two years. Yeah. Right. I’m 55 now, and memory recall is not what it used to be. I guess I’m writing that on paper, but my method may not be the most elegant… 😉

Yubikey. Not everyone has an electronic leash, or even lives in an area where such service is extant.

Plz change authentication methodes to include something for people not using smart phones like text message or some of the obove like ubykey ect

Please implement Yubikey FIDO U2F support for 2FA. It’s universally recognized as the most secure form of 2FA.

Is there any possibility, how to disable 2FA, when i lost my Google Authenticator code (trough support or anything else)? I am inside mailbox, but when i tried to disable 2FA and put the recovery codes, the answer is incorrect login credentials.

I prefer Yandex Key. Please investigate how it works for logging into Yandex.Mail on the computer. Never having to input your password or a 2FA code at login is a beautiful thing (on a computer). Now, if everyone could get onboard with this, life would be grand!

Please don’t ever make this compulsory. I understand the benefits, but it entails a link to your real-world identity (the phone). I would stop using proton immediately, even though in every other respect, it is the best thing going.
Quite apart from the anonymity issue, how are users in countries with oppressive regimes going to explain having that app on their phone? Even in the US, with its saintly respect for human and other rights, they could ask why you have proton, and even demand access to the account. They may not be able to do it to citizens, but they can to anyone else.

Yubikey!
Many of these 2FA apps are problematic if you lose your phone (lose your phone = lose access to ProtonMail!) or feature cloud backup (= increasing your attack surface). It would be great it ProtonMail could implement hardware token support.
OTP: https://developers.yubico.com/OTP/
U2F: https://developers.yubico.com/U2F/
N.B.: I am a paid ProtonMail user, and a Yubikey user– I have no financial ties to yubico. I just want good security. 🙂

If I enable this for my mail account, will it also ask for the code when using the VPN (which is running on the same account)?
0
Only the ProtonVPN webpage will ask for your 2FA code, the ProtonVPN app will not ask you to enter the 2FA code.

How is it 2018 and U2F such as with a yubikey is still not supported? Searching through other threads shows people have been asking for this for years, and with good reason.
In order for a user to bring their account’s TOTP security up to par with U2F, they need to make their authenticator itself (and its backups) only accessible via U2F which is an unwieldy process

I avoid downloading apps. Downloading things opens the probability of getting malware. I completed the 2 step authentification process with another email today which utilizes text messages to the phone as the 2nd step. Why can’t proton mail utilize such a method instead of requiring an app?
0
There is much higher risk of a hack using SMS than an app. Rather, it would be nice to be able to use a physical token like YubiKey.

for security reason. The “app” comes from Proton and is under control. Not the txt msg.

I don’t have a smartphone (just a simple flip phone), so I can’t set up two-factor authentication in ProtonMail the way it currently works. Why can’t ProtonMail handle two-factor authentication the way that other websites do, by sending a confirmation code to the phone number you type in?
0
We don’t support 2FA by SMS, but you can install a 2FA app on your computer.
0
Sms contains known critical security flaws. It is not legal to use this method in a secure email.

I am a new proton mail user. I forgot my username and password. Please advise me what to do. Also, I do not know what you mean by “recovery email”.

Though I ‘ve never used one, from my research and given the philosophical nature of protonmail’s security/’anonymity’ focus, I would say Yubikey! Doesn’t require the Identification that comes with a cell phone, which is good if, say, you have multiple protonmail accounts, and not all of them are meant to be linked to your public persona for whatever reasons (journalism, activisim…) A device like Yubikey with OTP would be ideal as if I recall you can set it up to authorize multiple accounts with multiple protocols, so with one key, unlinked to your contact information you could secure all of your proton usage, etc. great for authenticating an account accessed over the TOR network where correlating anoynmous web data flow with very much not anonymous mobile broadcast communications data.

Yubikey support would be great or just FIDO U2F

Voting for Yubikey and/or fido u2f standard

If you have reset your password, new encryption keys are generated while the previous ones are disabled. Because of this, your existing messages will become unreadable but you can restore them by providing the old password in the Settings > Keys tab on the web app. https://protonmail.com/support/knowledge-base/restoring-encrypted-mailbox/.

Where is DUO push integration please? Let us know please

Any authenticator app with support for the OTP protocol can be used with ProtonMail.
0
No option to use one-time use recovery codes. How do I disable two-factor verification without this option?
0
You use the recovery codes instead of the code generated by the app to log in. Once you log in with a recovery code, you will need a second recovery code to disable 2FA.

Please, add the “remember device” feature for the 2FA… It’s really annoying to have to type every time the 2FA code on the same personal device 🙁
0
Yubikey please. I’ve been using these for several years now and they are FIDO U2F.

I am using Lineage with F-Droid, I have not looked yet for 2FA, I just found this thread.
There are a lot of great ideas here.
Keep up the Awesome work PM.

Hi, the QR code is not showing up properly. I tried to enter the text into my authenticator manually but it fails every time. Not sure what is wrong with it.

I use Password Manager from MicroTrend, the ProtonMail app is supported with MicroTrend Password Manager. I recommend Password Manager for extra security.

+1 for SMS authentication, or ideally a 2-factor app with SMS as backup. Some of the commenters are concerned about security for SMS, but if you make it an opt-in feature then they can opt-out.
