Secure MFA

Local encrypted TOTP authenticator with offline backup and Android QR transfer.

Secure MFA keeps your time-based one-time passwords in a local encrypted vault inside Chrome. Add MFA records by scanning a QR code on the current page, importing a QR image, or entering an account and Base32 secret manually. Search, favorite, reorder, edit, and copy verification codes from a compact popup designed for everyday use. Back up selected or all MFA records to a passphrase-encrypted local file. Restore backups with duplicate detection, or copy selected records to the Secure MFA Android app through a user-initiated encrypted QR transfer and a separately displayed transfer code. Privacy by design: - No Secure MFA account - No product backend, cloud vault, or cloud sync - MFA data remains encrypted in your local Chrome profile - No ads, analytics, remote crash reporting, or tracking - No persistent website access or content scripts - Current-page screenshots are processed only after an explicit scan action, are limited to the user-selected region, and are never uploaded or retained The generated-password tool displays results only on the current page and never stores them. Available in English and Simplified Chinese. The interface follows your Chrome language.
