See it in about a minute

Opening views, filling a code, adding from a QR code, importing a backup, sharing a code, and locking. Demo accounts only.

Open it where you need it

  • Use the toolbar popup, a separate window, or the side panel (sidebar in Firefox).
  • Search, groups, pinned accounts, and a compact view keep long lists tidy.
  • See which account belongs to the site you are on, and fill its code with one click, a right-click, or a keyboard shortcut.
  • Optional buttons next to code fields on the sites you choose.

Add accounts your way

  • Scan a QR code from the current tab, your camera, an image, or the clipboard.
  • Paste otpauth:// links, or type the secret by hand.
  • Import plain-text backups from many authenticator apps, migration QR codes, and standard credential exchange (CXF) files.
  • Supports TOTP and HOTP with SHA-1, SHA-256, or SHA-512 and 6 to 10 digits, plus Steam (5 characters) and Battle.net (8 digits).

Private and protected

  • Accounts are stored on your device in a vault encrypted with AES-256-GCM. Set a password to protect its key: without one, the key is kept on the device next to the data.
  • Lock it with a password (Argon2id), a recovery code, and optional passkey unlock (not available in Firefox). Choose when it locks automatically.
  • Optionally require device verification before a code is used (not available in Firefox), and hide codes with a keyboard shortcut you assign.
  • No analytics, no ads, no developer server. The source code is public.

Backup and recovery

  • Encrypted backups, plus exports to otpauth text, CXF, and QR codes.
  • Sync between your devices through your browser's own sync (Chrome, Edge, Firefox), encrypted when the password lock is on.
  • Recovery snapshots, a 30-day trash, and an account change history.
  • Clock check warns you when your computer's time would make codes fail.

Share a code, not the secret

Send a link that shows the codes for the next 5 to 60 minutes, with an optional password. The link never contains the secret.

Privacy

There is no developer server, no analytics, and no ads. A clock check asks time.akamai.com, timeapi.io, and cloudflare.com for the current time, with no account data; you can turn it off. On Chrome, Edge, and Firefox, browser sync carries your accounts, encrypted with your vault key, through the browser's own sync service once you set a password lock; you can turn it off. Details are in the privacy policy.
