Hi everyone,

As most of you know, security and transparency are fundamental parts of Proton’s services.

We want you to be able to choose what happens to your personal information. Open and audited code means you can use this information to make an informed decision about who to entrust with your information.
We have now published the source code for all Proton Pass applications, which includes iOS and Android applications, along with the browser extensions for Firefox and Chrome-based browsers (including Microsoft Edge). You can find the source code for our Android and iOS apps here and our browser extension code 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.

You can read more about it on our blog here.
