Proton Mail v1.7.0 iOS release notes

We have released version 1.7 of the award winning Proton Mail iOS secure email mobile app. This release brings a new feature that has been much demanded from the user community, the ability to share directly to the Proton Mail App.


Select Proton Mail to send encrypted video from photos app

Proton Mail has long supported encrypted attachments. Now, you can share files securely directly from the app the file is in by selecting the “Share” option within the app. When selecting Proton Mail from the list of apps, you have the opportunity to share this file end-to-end encrypted through the Proton Mail App.

In case you cannot see Proton Mail in the list of apps when looking to share a file, you can hit More and then enable Proton Mail by switching the toggle button to green, like shown below.

Please consider supporting Proton Mail by upgrading to a paid plan. Your support allows us to continue to develop Proton Mail encrypted email as free and open source software.


Furthermore, it is still possible to register for the Proton Mail Mobile Beta Program. Not only is this a great way to support Proton Mail, you will be able to get early access to the newest mobile features before they are publicly available.
