BW Lite — yowmamasita

A tiny, unofficial client for Bitwarden and Vaultwarden. Around 2,000 lines of plain JavaScript, no build step and no framework. Open source: https://github.com/yowmamasita/bw-lite

It searches your logins, fills them, shows TOTP codes, saves passkeys and signs in with them, and offers to save or update a login after you sign in. Add as many accounts as you like on bitwarden.com, bitwarden.eu or your own Vaultwarden and they show up as one list with a colored tag for each vault.

Click into a login field and the logins for that site show up right under it. Ctrl+Shift+L fills the top one without opening the popup, and the login you used last stays on top. Logins inside iframes get filled too, but only when the frame's own address matches. Matching follows Bitwarden's match setting on each URL and its equivalent domains.

Passkeys are stored the same way Bitwarden stores them, so the official apps can use the ones you make here and the other way round. If you'd rather use your phone or a security key, one button hands the request back to the browser.

Your master password never leaves the extension. The vault key and the decrypted list live in memory-only session storage and are gone when you lock or close the browser. Nothing gets filled without a click or the shortcut.

Secure notes, cards and identities aren't supported. Two-step login works with authenticator apps and Bitwarden's emailed new device codes.
