Your 2FA codes, ready when login asks
Authenticator 2FA TOTP OTP MFA keeps time-based login codes in one focused iPhone app. Scan a QR setup code, enter a key manually, copy the current code fast, protect the app locally, and use premium backup, widgets, and Apple Watch sync when you want a larger setup.
Login codes without another app account
Authenticator does not require an app account. Add TOTP codes from the services you already use, protect access locally, and keep each service's recovery codes in a separate safe place.
Why download Authenticator
Two-factor authentication is only useful when the code is easy to reach at the exact login moment. Authenticator keeps codes readable, organized, and quick to copy without forcing you into a separate account system.
Use it for work accounts, finance apps, developer tools, games, social services, and any account that gives you a TOTP setup QR code or manual setup key.
- QR setup and manual setup keys.
- Current codes with refresh timing.
- Quick copy for login forms.
- Passcode and Face ID or Touch ID app authentication.
- Encrypted iCloud backup for Premium users.
- Widgets and Apple Watch sync for Premium users.
Built around real 2FA workflows
Authenticator supports the practical steps people need after enabling two-factor authentication: scan a QR code, add a manual secret key, keep common accounts pinned, rename codes, show a setup QR, delete old items, and copy a code before it refreshes.
The app also includes setup instructions and migration guides so users moving from another authenticator can understand the path without guessing.
Privacy and security facts
Camera access is used for QR setup. Face ID is used only to unlock the authenticator when local authentication is enabled. Local TOTP secrets and passcode data use Apple Keychain.
Authenticator can use product interaction analytics that are not linked to your identity and are not used for tracking, plus sanitized crash reporting. Real TOTP secrets, QR payloads, passcodes, salts, hashes, account labels, and issuer labels stay out of logs, analytics, and crash reports.
