You can activate biometric authentication by opening the app, going to the «Profile» section, selecting the «Biometrics» button and enabling the «Fingerprint or facial recognition» option.
Please note that, if you disable biometrics, you will need to use an alternative means of authentication (e.g. SMS code) to authorise 3-D Secure transactions.

For added security, we recommend keeping biometric authentication enabled as it provides a quick and secure means for authorising online payments and accessing the mobile app without having to enter additional passwords.
