AMS Auth

AMS Auth generates the six-digit, time-based one-time codes (TOTP) you use to sign in to your accounts with two-factor authentication.

Private by design:
• Your keys never leave your device
• Works completely offline — no account, no sign-up, no tracking
• Nothing is uploaded to any server

Simple and fast:
• Add an account by scanning its QR code, or enter the key manually
• A fresh, secure 6-digit code every 30 seconds
• Tap a code to copy it
• Rename or remove accounts anytime

Works everywhere:
AMS Auth is a standard authenticator, so it works with any service that offers an "authenticator app" for two-factor security — including Google, GitHub, Microsoft, AWS and more. Supports SHA-1, SHA-256, and SHA-512.

Your two-factor secrets are stored only on your device, in its secure storage. AMS Auth collects no personal data.
