Authenticator (2FA codes) with QR code scanning, auto-fill, sync between your computers and an invisible Google Drive backup.

Otapp is a two-factor authenticator (2FA) that lives in your browser. • Scan a QR code from the page, an image, a screenshot or your camera, or type the secret key • Codes (TOTP, HOTP, Steam Guard) filled for you on the sign-in page, with smart domain matching • Sync between your own computers through Chrome • Optional automatic backup to the private, hidden folder of your own Google Drive, with a welcome page to connect, review your backups and restore (add missing accounts or replace) • Optional master password: your keys are encrypted (AES-256) everywhere they are stored • 10 languages: English, French, Hebrew, Arabic, Spanish, Portuguese, German, Italian, Russian, Chinese Private by design: your codes and keys never go through our servers. The Drive backup uses only the app data folder and gives no access to your other files.
