Cipher - Offline 2FA Authenticator

Secure your logins with privacy-first two-factor authentication.
Cipher is a local-first authenticator app designed to keep your 2FA codes truly private and within your control. It generates time-based one-time passwords (TOTP) entirely on your device - no accounts, no cloud sync, and no external storage.

Your authentication secrets are encrypted and stored locally using secure iOS technologies. Cipher never uploads or shares your data - not even for backups - ensuring that only you have access to your 2FA codes.

Privacy by Design

Cipher was built from the ground up around one principle: your data should stay yours.
Unlike traditional 2FA apps that depend on online sync or user accounts, Cipher functions entirely offline. The app does not connect to external servers or log user behavior. Your secrets are encrypted and stored only on your device’s secure storage.

We believe privacy isn’t a feature - it’s the foundation. Cipher doesn’t ask for unnecessary permissions or collect any form of analytics. What happens inside your device stays there.
