Use Face ID or Touch ID to re-open the inspector app without re-typing your password each shift.
How biometric data is stored
Biometric templates never leave your device. The HDG app stores only an encrypted token in the iOS Secure Enclave / Android Keystore, which unlocks a refresh token bound to this device.
Recovery
If biometric fails 3 times in a row, you can always sign in with your email and password. Admins can revoke a device from the back-office.
