Using ProtonMail on iOS (iPhone)

ProtonMail on iOSEasily read, respond to, and organize all your messages on the iOS app. Our application for iOS gives you the same easy-to-use ProtonMail experience you expect from our web app on your iPhone. The ProtonMail iOS app is custom built from the ground up to provide the strongest security for your messages. You can also enable push notifications to ensure you’re always up-to-date on your emails.


Updates for ProtonMail’s iOS apps are tested by our dedicated iOS Mobile Beta group. Those in the Mobile Beta group play an important role in our iOS app development, as well as receiving access to ProtonMail’s latest features and the ability to communicate directly with the ProtonMail team.

ProtonMail in an iOS mobile browser

Most iOS devices can access ProtonMail through an up-to-date mobile browser by visiting ProtonMail works on most browsers, but you can check our list of recommended and supported browsers for more details.

ProtonMail with a third-party mail app

We don’t currently integrate ProtonMail with third-party email clients on iOS devices. Third-party email clients for iOS are not capable of the encryption and decryption processes ProtonMail performs to keep your data safe.

We also have a dedicated Android app for users with an Android device.

    to me it seems less important to create an iPhone App but to keep it secure!
    No compromises!

  2. Anon

    I would say iOS APP is no 1 on my list of getting protonmail into my life.
    The app should have the option of at least 2 or 3 protonmail accounts with easy switching (work/home/etc)
    Also have a phone pin when opening or finger print auth. So we dont have to type in the email decoding password (like my 20 character random num/letter/symbol combo). That would drive me mad. As most of us check email all the time!
    All I can say is make it good but make it faster! Please time is flying!

  3. DrL

    Count me in for a alpha/beta testing of the app ;)
    Keep up the great work !

  4. pha

    i would like to be in a testing team as well :)

  5. Kate

    I, too, would love an iOS app for Proton Mail. But security is #1. Not convenience.

  6. Anonymous

    Agree with above; security first – but an app so we can access easily would make ProtonMail more useable.

  7. Swordfish

    I’ll be a tester also.

    I seriously can’t believe how bad the quality of the interface we are stuck using via the IOS browsers has gotten. It’s to the point where text entry in email body fields is jerky and keeps moving the text cursor to random points in the text field, erasing and typing over what you have already written. The sizing of the text fields means if you exceed the immediate space provided, your typed text goes off the visible screen and it cannot be scrolled to or edited at all because one cannot see what is happening. The spacing between lines is completely random; one return, semi normal, another exaggeratedly far. These problems manifest both in current versions of Safari and less specifically but with the same issues sporadically in Google Chrome for IOS. Additionally, the mailbox decryption password field in Safari does not allow typing and sends one to the “reset password” form unless carefully tapped away from the normal beginning of the password field.
    Password entry is also difficult and the seeming issue with text entry makes entering the password problematic and prone to misentry, causing login issues.
    The situation of the combination of this and the lack of instant notifications has made things very, very difficult. I am completely dependent on your otherwise excellent system for my job, due to the security, and it has caused several serious communication issues with my employer, near misses were they serious enough, I would have been “written up” for this. Please improve this, or, you could make a very popular and positive decision and simply release the IOS and Android already and avoid the negative press of so many people like me who believe you have the best email system existing and will be loyal completely despite serious usability flaws who cannot but help feeling somewhat manipulated by the beta releasing process and worried that even if we pay for the beta, we will not get the link in a timely manner despite paying.

    Thank you for your attention to these matters. I hope improvements can be made and the situation with frustrated users deescalated.

  9. Ryan

    Yeah yeah I agree with the anon y mouse above. The interface on the IOS browser has serious problems. It is not recognizing where my finger touches down and thus all sorts of unintentional things happen :(

  10. Why_cufs

    I would like to beta test but I don’t don’t want to pay to do so especially for something that may not even work correctly

  11. Peter

    “We will go live on the Apple Store on 18th February 2016.”
    It is still beta on 1th Mar.
    When will you go live?

  12. Kennedy

    Is this still in beta? March 10th today…

  13. ProtonMail Support

    The app is available for free on the App store.

  14. Bryan Klingler

    I do not check my e-mail as often as I should. Is there a way I can get a text notification that I have received an unread e-mail to my iPhone?

  15. ProtonMail Support

    At this moment you can add a notification email address that will notify you when you receive new email. For more information, please visit this link:

    Such a shame there’s no iOS7 version. Why only make it available for people who can afford to change their phone every 18 months? Think about all the people using refurbes iPhones in Latin America and Aftica – is their privacy less important than rich Swiss people?

  17. ProtonMail Support

    We would love to support iOS 7, but unfortunately, we don’t have enough resources to add iOS 7 support.

  18. Ed

    How do i switch between accounts on App
    Example if i use your service with my domain i may have many users i make how can i check and send mail form all of them without logining in and out of each account like yandex allows ?

  19. ProtonMail Support

    This option is currently unavailable. Our team is working on adding this in the future.

  20. Ami

    On my iPad I am missing a possibility to move several mails (from the same sender) from inbox to a folder in one move instead of having to open each mail and then move them separately. Have I missed something, or is that not possible?

  21. ProtonMail Support

    You can tap and hold on a message for it to become selected. Once it is, you can select other messages, and then apply an action to all of them (Move or apply a Label)

  22. Kris

    iOS 9.3.4 on an iPhone 6.

    I have it set up to validate application access with the touch id (fingerprint) but this frequently fails forcing me to enter long passwords on a tiny keyboard. This is not a good situation as I don’t always have my computer available to log in – which is why I set up the iPhone in this manner. Is there something I should be doing different?

  23. ProtonMail Support

    Hi Kris,
    Sorry for the inconvenience. We are working on fixing this problem.

  24. bobby

    I just got an email requesting feedback for the protonmail 4.0 release. The iOS appstore version says 1.4. Are us non-beta users really that far behind?

  25. ProtonMail Support

    Our latest official mobile application is 1.4. The 3.4 version is regarding the web app only.

  26. Paul

    In IOS you can easily share photos, videos, contacts etc from any app with a Share button. But on my iPhone I cannot select the protonmail app to send the content to (just Whatsapp, Mail, etc.). Can I/you make this happen somehow?

  27. ProtonMail Support

    We are planning to implement this in the future.

  28. Evgeniya

    Hello. Do you support print message on the printer on iOS?

  29. ProtonMail Support

    We are planning to implement Print option on the iOS app in the future.

  30. Evlampiy

    Hi! I have many protonmail account. But in ios app I can use only one, yes or not?) Thank you

  31. ProtonMail Support

    Yes, you can only log in to one account on the iOS app. To switch accounts, you will need to log out of the current account.

  32. Kim

    My signature is copied into each email with a different format that in the settings. The spaces are taken out so that it looks crammed together and unprofessional. I can add spaces but don’t know why this is happening. Anyone?

  33. ProtonMail Support

    We are working on improving this behavior, and it should be fixed in one of the future updates to our iOS app.

  34. Koen

    Hi ProtonMail, I’ve been happily using your service on my iPhone with the ProtonMail app. While the app gives an almost superb experience, it’s just not the same as a native mailclient. Proton obviously doesn’t have the immense resources Apple has. So kudos for doing such a great job!

    While updating to the newest iOS (11.2.2) I noticed Apple implemented PGP (seems like a proprietary version called ‘Apple Product Security PGP’). Source:

    Does this change anything? Is there a chance for third party mailclient support on iOS in the near future??

  35. ProtonMail Support

    At the moment we are focusing our efforts on our own ProtonMail app for iOS and have no plans for Bridge support on iOS yet.

  36. Joan deguia

    Can you help about the “Unable decrypt message” i can’t read and open an attachment. What do i need to to?

  37. ProtonMail Support

    Please contact our support team at, via the report bug button or using the support form at

    Have you planned in the near future to allow when adding a contact via the ios contact application that the added entry be synchronized with the proton mail address book.

    Ideally :

    I add a contact via protonmail webmail: sync to IOS App Contacts
    I add a contact via the IOS contact apps: sync to protonmail’s webmail and Ios Proton app
    Not sure but maybe … / … I add a contact via Proton mail application on Ios: sync to Ios app contact

    Very good day

  39. ProtonMail Support

    We do have plans on adding support for contacts sync, however, we cannot speculate on an ETA.

  40. Roger

    Good morning,

    The feature ToFit mentioned (syncing Protonmail contacts between the web/cloud/Protonmail app and the iPhone’s built-in Contacts app) would be a fantastic feature if you could add that at some point. Thanks for all the work you are doing – it is very appreciated!

  41. Anonymous

    The ability to switch between two accounts would be incredibly beneficial.

  43. Fraser

    Does this mean I can’t get Proton Mail emails to my iPhone like regular emails?

  44. ProtonMail Support

    You will need to use either the ProtonMail app for iOS or our webmail.

  45. mig


    Notifications (in blocked screen and bubble) in the iOS app stay even after I’ve read those messages in my computer. The only way to clean those is to open the app so that it gets synced.

    Shouldn’t it sync in the background?

  46. ProtonMail Support

    We currently don’t have this implemented, but it will be available in the future. For now, you have to open the app to update the badge counter.

  47. Mark

    I would like to get assistance with setting up ProtonMail through Apple iPhone through IMAP/POP just so I don’t need to go through an app interface and so I may add an extra layer of security. What is the Incoming/Outgoing Mail Server Host names, user, and password? Once I get out of the first part of schooling I DO plan on purchasing the full package you guys offer and supporting you guys! Thank you for maintaining your high level privacy and security!

  48. ProtonMail Support

    Unfortunately, you cannot use ProtonMail in third party apps on a mobile OS. You will need to use the ProtonMail app from the App Store, or the browser version.

  49. Bert


    I noticed that when TouchID is enabled and an incorrect fingerprint is used, you get the option to enter the IOS passcode. Now if someone has my pincode, they also have access to my account. To compare this with Lastpass (or my bank app), you can only use TouchID. When an incorrect fingerprint is used, you have the option to enter the main password and not the IOS passcode. If a new fingerprint is added, you also need to enter the main password.

    Is it possible to only use TouchID or are there any plans on implementing this in the future?

  50. ProtonMail Support

    The PIN for the ProtonMail app is set up separately from the PIN for iOS. If someone has your iOS PIN, they won’t necessarily know the PIN for the ProtonMail app.

  51. Amy

    Hi – I finally installed the iOS app (I don’t normally like installing apps, they bring too many problems) because otherwise I was having to log in again every time I switched to another browser tab, but man, the app is a terrible ride for typing. S. L. O. W. W. I. T. H. L.E.T.T. ERSAPPEARING VE. R. Y. JERKI. LY. I mean I know that my connection isn’t fantastic, but it’s as good as it’s going to get in a non-urban US area, and browser typing seems fine, fluent. What’s the problem?


    I’d really like for protonmail to be my main mail service, but you guys are not making it easy. So far the only reliably good experience is on desktops, and I’m….mobile.

    Dear All,
    is it possible to migrate proton mail mails to iPhone mail environment? I do not want to use the application.
    Thank you,

  54. ProtonMail Support

    No, you cannot set up a ProtonMail account in a 3rd party email client on mobile devices.

  55. Rui

    Hello to all,

    I would like to know if it is possible to change the way links are open from ProtonMail, currently in my device they open in Safari but I would like to be open in DuckDuckGo, how do I set it up?


  56. ProtonMail Support

    You cannot set another default browser on iOS, this is an OS limitation.

  57. Steven

    Has anyone else been having issues with Touch ID on iPhone? Ever since upgrading to 13.1.2 it takes me five or six tries to actually get past the login screen. I open the app, get prompted for Touch ID, use my fingerprint, Touch ID clears but it leaves me at the login screen. After several tries it will generally let me in. I’ve tried uninstalling and reinstalling, as well as changing authentication types, but nothing is helping.

  58. ProtonMail Support

    This is an issue on iOS 13, it should be improved in a future app update.

  59. Peter


    Is there a way to have only a select number of email addresses show within the iOS app rather than all of them?

  60. ProtonMail Support

    Unfortunately, no. But you can use Folders, Labels and Filters to better manage your mailbox.

  61. Louis Fiol

    I can’t log in. I’ve been getting logged in automatically on the mobile app for quite a while and apparently I can’t seem remember my username and/or password. I tried checking if my username was correct but my backup email never received anything. I even tried to reset my password after numerous attempts but am not getting a reset email. My email is [hidden] My backup is [hidden] Please help. I’ve tried everything. Thanks

  63. Alan

    Is it possible to condensate messages with same subject in iOS app? Can’t find this feature in settings…

  64. ProtonMail Support

    Not at the moment. Conversation mode is coming to a future app update.

  65. Tim

    Please, please add support for importing calendar *.ics attachments into the ios claendar app. My only workaround now is to forward the attachment to a gmail account, which seems like removing the whole point of a protonmail account!

  66. Jon

    Prior to losing this is account I lost two gmail account in similar fashion so some f-%^* hacker is targeting me and this is so wrong they can even do this. Please investigate whoever is accessing my account currently and you’ll gone the culprit. Whoever is behind this is very good is guess Black hat society good. And why are hackers glorified in today’s day in age where 73% of Americans are victims of this cyber crime???…
