We have released version 1.7 of the award winning ProtonMail 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 ProtonMail App.

Sharing

ProtonMail 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 ProtonMail from the list of apps, you have the opportunity to share this file end-to-end encrypted through the ProtonMail App.

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

Please consider supporting ProtonMail by upgrading to a Paid Account. Your support allows us to continue to develop ProtonMail encrypted email as free and open source software.

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