Proton Pass
An open-source, end-to-end encrypted password manager from the Proton Mail team. It has a free plan.
Why it's a strong pick
Proton Pass has a free plan with unlimited logins, notes and cards on unlimited devices. Proton says it is open source, end-to-end encrypted and has no ads and no trackers. The trade-off: the free plan has limits on hide-my-email aliases and 2FA items. More of both need the paid Pass Plus plan, so check current limits.
What it does
Proton Pass stores and syncs logins, notes and cards across your devices and fills them in when you sign in. It makes strong passwords and stores passkeys. It also warns you about weak or reused passwords on the free plan. You need a Proton account, and signing up is free. Proton describes all fields as end-to-end encrypted.

Who it's for
Proton Pass suits people who want a free plan with unlimited logins and devices, and who like a vendor that publishes its code and its audit. If you need many aliases or lots of built-in 2FA codes, expect to look at Pass Plus. If you want to keep 2FA codes in a separate app, see Authenticator.sh. For another free, open-source option, see Bitwarden.
What is free in Proton Pass, and what needs Plus?
The free plan covers unlimited logins, notes and cards, unlimited devices, a password generator, passkeys, weak and reused password alerts, plus limited aliases and 2FA items. Proton lists unlimited aliases, a built-in authenticator, vault sharing, dark web monitoring, file attachments, emergency access and a CLI under Pass Plus. Check current limits.
Is Proton Pass open source and audited?
Proton says its apps and browser extensions are open source and end-to-end encrypted. It also published an audit by Cure53, which covered the mobile apps, browser extensions and API after launch. Proton quotes Cure53 calling the overall state of security "commendable". That is Proton's own account of the audit, so read the report.
What permissions does Proton Pass ask for?
Check the install prompt on the Chrome Web Store listing before you add it. A password manager has to read and fill forms on the sites you visit, so expect a broad request. Permissions can change between releases, so read the prompt again after big updates.

Good to know
The free plan is generous on logins and devices, but aliases and 2FA items are limited. If you plan to put all your 2FA codes in it, count them against the current limit first. Turn on two-factor authentication for your Proton account and keep a recovery option, so you are not locked out.
