Proton Pass Extension: Review & How to Use (2026)

Proton Pass Chrome extension

Proton Pass stores passwords, generates hide-my-email aliases, and includes a built-in 2FA authenticator, all encrypted end-to-end. It's best for people who want unlimited free password storage without ads or data selling. The catch: some conveniences other paid managers offer, like advanced sharing or vault health tools, sit behind Proton's paid plans.

What Proton Pass does

Proton Pass stores your logins, notes, and 2FA codes in an end-to-end encrypted vault and autofills them as you browse. Unlike some competitors, it encrypts your full login details, including usernames and website addresses, not just the password field. It also generates hide-my-email aliases so you can sign up for services without exposing your real inbox.

Proton Pass free vs paid

The free plan covers unlimited logins, autofill, password generation, encrypted notes, and email aliases across unlimited devices, with no ads or data selling. Paid Proton plans add extras and bundle Pass with other Proton services like Mail, Drive, Calendar, and VPN for people who want the full privacy suite.

Is Proton Pass safe?

Proton Pass needs access to your login credentials to autofill them, which is inherent to how any password manager works. Its apps are open-source, meaning the code can be independently reviewed, and it's built by the team behind Proton Mail, which operates under Swiss privacy laws.
