The best

This is a complete add-on for password security. I've been using Proton products for years, and none have ever let me down. They haven't sold telemetry data to third parties. The Firefox add-on hasn't shown any incompatibility issues; on the contrary, it works flawlessly and hasn't given any errors.

I love it. It's so convenient and I trust its security. I can even upload my 2FA secret keys into it and use the one-time pass codes my authenticator app uses directly from Proton Pass. Good stuff and saves time.

Moving from other password managers, this is the best one I've found. Improvements can be done, but it's very good overal.

I am a lifelong fan of Proton's services, and this browser extension does not disappoint. Very quick to suggest autofill, autosave, and create new passkeys. Overall a solid W.
