Your device should detect and offer you the option to use face or fingerprint ID to log in to bOnline phone after your first login. However, you can also update this feature using the 'Features' section under your app 'Settings'.To use, simply open your bOnline phone app on your iOS or Android device and place your finger on the fingerprint image. Face ID works in the same way where you just click the face ID image and hold the device near your face.NB: Please log in initially for the first time before using this feature. For further assistance please contact our onboarding team at voipcare@bonline.com
