Biometric authentication is a security process that involves using some part of your physical body to authenticate you. In the case of Xaman (formerly Xumm), a fingerprint or face scan.
There are couple of things that you should be aware of before you configure Xaman to use biometrics:
Xaman does not create or store any biometric information. Instead, it relies on your phone to manage all biometric information.
Configuring Xaman to use biometrics does not replace your 6 digit passcode. You can still use your passcode to access Xaman.
On some older phones, you must configure both your fingerprint and your face scan on your phone before Xaman will enable biometrics. Configuring one or the other will not work.
Some Apple phones, (iphone 12, 13 and 14) do not have the option to setup Touch ID. With those phones, you can only configure Face ID so Xaman will only support Face ID in those cases.
As long as you have successfully setup your fingerprint and/or face scan on your phone, enabling biometrics can be easily done by:
1) Launching Xaman and pressing the Settings button.
2) Tapping the Security option.
2) Tapping the Biometric authentication button.
Once biometrics has been enabled in Xaman, it will continually check the biometric configuration on your phone to see there have been any changes. If the host parameters of biometrics change (e.g. iCloud account security settings updated, fingerprint/face added/removed, etc..) Xaman will automatically disable biometric authentication and revert exclusively to the six digit passcode configured during the initial installation. We did this because an attacker with access to your phone might be able to add their own fingerprint to your device, thus granting themselves access not only to your phone but also to your Xaman wallet.) If this happens, just disable Biometric authentication in Xaman, reboot your phone, then launch Xaman and re-enable Biometric authentication.
In many cases, just toggling Settings > Security > Biometric Authentication off then back on is enough to resolve most issues.
Samsung phones
On some phones, you may encounter the follow message,
As mentioned above, you can try configuring BOTH a Fingerprint and a Face ID configured.
On most Samsung phones, here is how to configure this:
1) Go into Settings on your phone and select Biometrics and security.
Make sure you have both face and fingerprints setup.
