## What is CSMS Auth?

CSMS Auth is a 2FA app that generates time-based one-time passwords (TOTP). Add accounts by QR or by hand, manage many accounts, and copy a code in one tap. Keys stay in the on-device keychain and are not uploaded. Lock with biometrics or a gesture; the app locks when it goes to the background. Home Screen widgets and the watch can show codes. Use it for work systems and common TOTP services. Keep your own key backups; uninstalling or resetting the device may lose them.

## Version history (last 2 releases)

### 3.0 Duo — 2026-10-21

Support for iPhone Duo. The outer display stays in portrait, with a side toolbar. Unfolded, landscape splits left and right, and portrait splits top and bottom, so the code and the Systems Board appear together. On a regular iPhone, the interface is unchanged.

### 2.0 — 2026-10-15

No release notes.
