Proton Pass’s code has been made open source and passed an audit carried out by the security experts at Cure53.
Hey,
Proton Pass is open source and has now passed an independent security audit (by Cure53). The Android and iOS apps source code can be found here, the browser extensions source code for Firefox and Chrome-based browsers (including Edge) can be found here.
Proton has also completed an independent security audit conducted by Cure53 for all Proton Pass applications and browser extensions, along with the Proton API. This was a “white box” audit, meaning the security researchers were given full access to the Proton Pass source code, along with full access to Proton Pass engineers.
More information can be found in the blog post over here. The audit report can also be found in the blog post.
If you use an IMAP email client the ProtonMail Bridge works great on Linux. VPN works well from the command line, though the GUI is still pretty clunky and RAM heavy and either way they really need to make Wireguard and Stealth available on Linux already.
There is zero support for drive under Linux which is the major reason I haven't migrated my workspace org yet. I'd like to ditch Google, but I automate backups with rclone to gdrive and that workflow can't currently be replicated under proton
The official ProtonVPN app on Linux has a lot of problems, like a memory leak that exists since years now. At least for me, only the cli without graphical interface works (but does so very well after some tinkering). The lack of Linux support (especially no Linux app for the drive) has frustrated me to the point I am regularly questioning my Unlimited subscription.
But I agree in general, you can get around a lot of the Linux limitations by using browser extensions like the ProtonVPN one. And overall the addition of new services and great security outweighs the lack of Linux support.
