Is it safe to use biometrics?

When using biometric authentication, the access code from the card is stored in encrypted form in the device's secure storage: the keychain. In this case, the keys do not migrate anywhere from the card. The access code, meanwhile, has no functional value without the card. It is important to note that this function is optional and can be disabled at any time or not enabled at all. You can read more about how biometric authentication works in our blog article.
