Proton Pass

Encrypted password manager with email aliasing for privacy-conscious browser users.

Proton Pass stores logins, notes, and cards in an end-to-end encrypted vault and autofills them in the browser, with built-in two-factor codes and hide-my-email aliases that mask your real address at signup. It is open source and run by Proton AG in Switzerland. The free plan covers unlimited logins and a capped number of aliases, and Pass Plus adds unlimited aliases and dark web monitoring.
