AuthPeek – 2FA Authenticator & Code Autofill

Authenticator for Chrome: generates 2FA codes and fills them into login pages. Encrypted sync across your browsers, no servers.

AuthPeek is an open-source authenticator for Chrome. It generates the same 6-digit 2FA codes as Google Authenticator™ and fills them into login pages for you, so you sign in without reaching for your phone. Your accounts are encrypted with your password before they are saved, and AuthPeek has no servers: nothing is sent to the developer. Add accounts • Scan the QR on a site's 2-step verification setup page, or upload a screenshot of it • Paste otpauth:// links or type the secret key • Import from Google Authenticator™ with its Transfer accounts QR Auto-fill • On linked sites the field is filled the moment the page asks, whether it is one box or six • Two accounts on one site?

No servers, no tracking, no ads Google Authenticator is a trademark of Google LLC. AuthPeek is not affiliated with Google.
