@helenslunch No - they don’t. They have their own Password manager.
Proton Pass is still in beta and lacks many features! Cannot recommend it!
Better use 1Password, Bitwarden, Strongboxsafe or Apple’s Passwordmanager.

Proton Pass maybe will get his time - but not now. I think it needs 1 or 2 more years to become feature rich and stable.

@helenslunch he ist proton partner. He has to write this 😎

@isVeryLoud that’s true.

@Heavybell It is fully Electron.

@Apollo2323 macOS same.

@HEXN3T Bitwarden connected to SimpleLogin does provide Email Masking - or am I wrong?
