“ProtonMail offers encrypted email, which makes it virtually impossible for anyone to read it except the sender and the recipient.” Wall Street Journal
ProtonMail is the world’s largest encrypted email service with over 1 million users. The ProtonMail secure email app for iPhone and iPad brings easy-to-use email encryption to your mobile device by seamlessly integrating PGP end-to-end encryption.

Ratings and Reviews
Great service, lacking a few features to make it a home run
ProtonMail is an excellent service for both the privacy conscious and the masses. The reason so many email providers are free is because it the provider is in a privileged position to scan all of your emails. ProtonMail sets itself apart from the rest, and doesn’t read your email, or store it in a format that they can access.
I would highly recommend a paid plan, even if you don’t need any paid features. Pay for your usage with your money, not your data.
However, the absence of one feature makes the ProtonMail experience painful (-1 star): No notification dismissal syncing. If I read an email on my iPad, it will still show the notification on my phone until I open the app. Almost every other mail/chat app has notification dismissal syncing, but when I asked ProtonMail about implementing this feature, they said it was not possible. If they found a way to add this feature (and it’s possible considering other services can do it), then this service would be a true 5 stars.

Hi! Thank you for your feedback. We plan to improve our notification synchronization in the near future. We would appreciate if you consider updating your review once this feature is released.
Face ID not working to login to App
It seems that Face ID is not working to login to the App. I’ve tried multiple times by first logging in manually and then enabling Face ID.
But every time I logout and then try to log back in, Face ID is not initiated. I login manually again and see that Face ID is disabled. I enable it again, but it goes back to being disabled every time I close the App.
Is the Face ID function only for access when the App is logged in, or is it designed to allow fore using Face ID to login when initially opening the app?
Reply to developer: I saw your reply and do not agree because after three days of trying, the App will now allow me to login with Face ID. I don’t know what changed in the App, but I just kept doing the same thing. I have now installed the ProtonMail App on my wife’s phone and Face ID is working properly too. Increased my rating from 3 to 4 stars.
Update #2: thanks for replying back to feedback so quickly! No, I did not need to choose or select any keychain or password icon. When the app is completely closed (swiping up from the bottom, on both an iphone X and XS Max, to close the ProtonMail app), then pressing the PM icon only once to open the app: FaceID now comes up immediately and after correct recognition, the PM app is unlocked and accessible. It was not like this when I first installed the app, but now it works this way.

Face ID can only be used for unlocking the app after you’re already logged in, and settings will go back to default ones once you logout.
That is done by security reasons: we do not want to keep any user-related data on device after logout. Storing credentials required for login would be totally insecure in case your device is stolen and hacked.
Update: probably, you mean FaceID auth initiated by Password AutoFill feature, that happens when you tap ‘🔑 Passwords’ button above the keyboard? That is system level feature and not part of our app. In order to make it work, you’ll need to save login and password in iCloud Keychain - Apple’s password manager - in device settings:
Settings > Passwords & Accounts > Website & App Passwords
Excellent email service, private and secure
If you value security and privacy use ProtonMail. Even the free accounts are private and secure. They do not sell your information or scan your emails for keywords to send ads. I have both a free account and a paid account and they both work great. I have been using protonmail for a few years now and I love it. The app features are fine. It has all the necessary features plus security and privacy. Some people are too picky they want an app that covers everything and I don’t think there is an e-mail app that has every feature and still keep you info private and secure. I’ve read some of the reviews, and I have not had any issue with crashes or glitches. Some reviews don’t sound like they are about this app. Not sure what some people are doing.
