CSMS Auth
Secure 2FA authenticator
Free · Designed for iPad. Not verified for macOS.
Add keys by QR or by hand. Manage accounts. Lock with biometrics or a gesture. See codes on widgets and watch. Secrets stay on device. Copy in one tap.
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.
