Mobile app biometric verificationBeta

Learn about biometric verification for Retool Mobile apps.

Biometric verification enhances the security of your Retool mobile apps by adding an extra layer of identity verification using biometric data. After users log in, they are prompted to verify their identity using biometrics each time they bring the app to the foreground. Biometric verification does not replace your existing login mechanisms.

Enable biometric verification

Go to Settings > Mobile Advanced Settings and toggle Retool Mobile: Enable user verification via biometrics on.

To allow users to use screen lock credentials (e.g., passcode or pattern) as a fallback to biometrics, select Retool Mobile: Enable user verification via screen lock credentials. The device's operating system determines when this fallback is used, and may prompt for the fallback after consecutive failures or if biometrics are unavailable.

You can also enable the Privacy Screen which obscures the app preview when viewed from the mobile device's app switcher.

Verification behavior

The first time users log in to Retool Mobile apps after enabling biometric verification, they are prompted to set up biometric authentication—e.g., enrolling fingerprints or enabling face recognition. For future logins, when users bring the app to the foreground after logging in, they are prompted to verify their identity using biometrics.

If biometric validation fails after three attempts, users are logged out of the app.

Security

Retool does not store any biometric data. Biometric validation relies on the security features of the underlying operating system to securely provide and handle biometric data.
