    But after having confirmed that I am a real person, the system had trouble. Now I can’t create again the account because it already exists, but in the same time I can’t enter because of the missing confirmation. Is it possible to confirm it and uxe the created account?

    Why can’t I access older emails?

    I can only access emails on the first page, and nothing prior. This is NOT useful.

    I need to be able to scroll back through the emails I have received previously to those on the first page. I have used a number of webmail services in the past, and this is the first time that I am having to ASK to access earlier emails – this has always been automatically included in the past. Is there a reason why you have left it out?

    Thank you,

    Only 50 messages/conversations are displayed per page. You can go to the next page via the left/right buttons in the top right corner, where the page indicator is located.

    I just have installed your Android app on my LG G3. I’m pretty sure about username & password but the app returned me an error (Invalid username or password). May it be because the default domain is “” while mine instead is: “”?

    I signed up for a craigslist account but now I can’t receive my emails. Is something going on with them? Like why can’t people really reply back to the ad for items online on their website?

  21. ProtonMail Support

    At this moment, you cannot setup separate mailboxes and passwords for the custom domains addresses. Also, you cannot add your custom domain on multiple premium ProtonMail accounts.

    We are working on adding these features in the near future.

    Dear ProtonMail Team,

    1. Why do you utilize cell phone numbers when registering a new account?
    2. Why do you send SMS text (account activation code) with words indicating that the SMS was sent from ProtonMail or on behalf ProtonMail. It’s very insecure to add additional information rather that only activation code. Please, remove unnecessary information.

    When logging in with my second password the login box changed a bit and said something about losing all my data if I forget my password and asked me to type in “Danger” to the password box. I did not do it because it looked like a scam.

  37. ProtonMail Support

    Resetting your Mailbox Password is permanent, and will render all encrypted messages in your inbox. By entering the word Danger you agree that all your old messages will stay permanently encrypted.

    Hello, could you help me please, I have emptied everything in the trash bin and it has deleted the emails I had labled…
    please tell me there is a way on undoing my mistake?

  39. ProtonMail Support

    Unfortunately, once you delete the messages there is no way of retrieve them back.

  40. Dinitro

    Can’t log in! “Too many recent invalid login attempts” But ALL my recent login attempts have been successful as normal; there haven’t been any unsuccessful ones. And if there had been (such as someone trying to hack my account), blocking me from accessing it with my legitimate passwords surely doesn’t help me.

  41. ProtonMail Support

    Sorry to hear that. You will be un-banned in the next few hours. Can you please try again later?

    Does Protonmail *not* work with certain Firefox addons, or versions of Firefox? Because I can login, and send emails, but I can’t see any emails in my SENT or INBOX (4) ‘folders’ even though there should be messages there.

    ProtonMail works with most modern browsers. We recommend you use the latest versions of your browser for maximum security. Can you please contact us if you are experiencing any issues, at or use the Report Bug button?

    How do I view email content on a mobile browser which happens to be Safari/IOS? Presently I am getting encrypted emails from a physician that I cannot decrypt via IOS/Safari mobile because the screen has no active buttons on the IOS device. Although I have opened/stablished a mobile mil account (grabbing at straws) I do not want to establish a new email address with the ProtonMail sender. Basically I want the ProtonMail senders email to my Outlook acct accessible on a PC and mobile/IOS device. For what it is worth I have not attempted to decrypt an email on a larger IOS device like an iPad.

  52. ProtonMail Support

    Can you please try to contact us from the report bug button? Please include a screenshot from your problem.

  53. ProtonMail

    Your web-based e-mail login hangs after entering the decryption password. I will not take “use a different browser” as acceptable. I use firefox stable, developer, and alpha being that the central intelligence agency bought sun microsystems (owner and developer of java and javascript) with it’s company oracle, and has weakened the language for exploiting it’s security. I sandbox windows in more secure operating systems and will advise you of the flaws in your security starting with the previous facts stated alone. I expect at the very least a solid reply regarding everything stated. People is this the type of Computer/Network Security Administration you trust your privacy with? Not even a reply to mathematically verified facts? I cite PHD Charlie Miller’s skills as well.
    Moderators have cowardly deleted 3 posts pertaining to this topic without a reply. Shills.

    Hi ProtonMail,
    I would like to create an account.

    Screen “Are you a human”:
    – ReCaptcha: just “loading…”, waiting and waiting and nothing else…
    – SMS: Never received the SMS
    – Email: I received the code; then typed the code but an error appeared on the next screen – point 1/5 (before the account creation). So I restarted the process, but now protonmail does not want to send me another email on my email adress (“Email verification disabled for this domain name”).So I used my second email adress and now I have the same result.

    So YES I’m a Human and I can’t create an account on ProtonMail !!!

    Sometimes the settings of the browser may interfere with the creation of the account. If you need assistance please contact us on

    The “Report A Bug” button (URL: doesn’t work, nothing happens when clicking on the drop-down option for bug reporting.

    What I wanted to report is as follow:
    Hardened browser with restricted web site font dowloading setting (fingerprinting issue) doesn’t allow those tiny “@font-face” (aka. font icon) icons next to a text/button to show up, instead a tiny box with a HEX digit inside it appears.
    It’s something according to this Mozilla support pos which solved my problem:

    ps. I agree with the previous post, I did also chose “ReCaptcha” to verify as Human but it got stuck with “loading…”, the other options worked though for me.
