Q17. Why my Mobile Security Key is deactivated?

For security reasons, the Mobile Security Key may be deactivated when:

the biometric data on your device is changed (e.g. add or delete fingerprints or reset facial recognition);
you have activated Mobile Security Key on other devices;
your Fubon Internet Banking / Mobile Banking Services have been terminated;
you have inputted an incorrect Password for 5 consecutive times;
there are 5 consecutive failed facial recognition match attempts;

If your Mobile Security Key is deactivated, an e-mail/SMS notification will be sent to your registered e-mail address/mobile phone number from the Bank. You will need to re-activate for the Mobile Security Key if you wish to continue using the service.

Q18. Is fingerprint/face recognition authentication safe?: Fingerprint/face recognition can provide a high level of security and protection for identify verification. Only fingerprint(s) / face recognition stored on your device can be used to logon to Mobile Banking. However, you are reminded that when using facial recognition, there is probability of false match due to certain circumstances, e.g. twins or siblings that look alike or “Require Attention for Face Recognition” function in your device settings is disabled. Please read the Terms and Conditions carefully and accept the associated risks and consequences before you activate facial recognition.
Your fingerprints / face recognition data will not be stored in the Fubon Bank Mobile App or kept anywhere within the Bank.

Q19. Can someone else logon my Mobile Banking if their fingerprint/face recognition is stored on my mobile device?: Yes. Any fingerprint(s)/ face recognition(s) stored on your mobile device, now or in the future, can be used to logon to Mobile Banking Service when you have activated your Mobile Security Key. Therefore, the Bank strongly recommend you to only store your own fingerprint/face recognition on your mobile device and should not store or allow any third-party fingerprint(s)/face recognition to be stored on your mobile device.
