Authenticator – Keep Your Accounts Secure

Authenticator is a modern and reliable two-factor authentication (2FA) manager that works entirely offline. It generates time-based verification codes used when signing in to popular online services, and allows you to store all your accounts securely in one place. All data is kept only on your device and is never sent to any server.

You can add accounts by scanning a QR code or manually entering your secret key, and protect your logins with verification codes that refresh every 30 seconds.
