Authenticator

Authenticator — simple and reliable two-factor protection

Turn on two-factor authentication and protect your accounts for real. Authenticator generates one-time OTP and TOTP codes right on your device — far safer than codes sent by SMS, and it works even without an internet connection.

It works with any service that supports one-time passwords: email, banking, social media, developer and work tools. If a website offers sign-in with a TOTP code, this simple TOTP authenticator will handle it.

Add an account whatever way suits you: scan a QR code, enter the secret key manually, or open a setup link. Nothing extra — the app does one thing and does it well.

What's inside:

- One-time codes (2FA) to sign in to all your accounts

- Three ways to add accounts: QR code, secret key, and link

- Hide codes on the home screen and when copying

- Fully works offline

Your keys stay with you alone.
