Sentinel Authenticator

About

Sentinel Authenticator brings your two-factor authentication (2FA) codes to your browser. Sign in with your existing Sentinel account and view live, time-based one-time codes (TOTP) for all your services — no more reaching for your phone every time a site asks for a code.

FEATURES

• One-click copy — copy any code straight to your clipboard.
• Smart autofill — drops the current code directly into the 2FA field of the site you're signing into.
• Biometric lock — unlock with Face ID, Touch ID, or Windows Hello via your device's platform authenticator, instead of typing a password every time.
• Sign in your way — email & password, or continue with Google or Apple.
• End-to-end encrypted — your codes are encrypted on your device before they're ever stored, and only decrypted locally in your browser.
• Synced automatically — codes added in the Sentinel Authenticator app show up here too.
• Light and dark themes.

Requires a Sentinel Authenticator account — you can create one directly from the extension.

Your 2FA secrets are encrypted client-side before they leave your device, so they're never readable by anyone but you.
