Use of voice recognition / voice biometrics to authenticate a customer when calling contact centre

[Shano1]

Does Sky utilise voice recognition / voice biometrics as an authentication method for customers? I have searched my account for details on security, Support, Contact Centre etc and nothing there. I have tried calling the contact centre and cannot get by the menu options. I have tried the virtual assistant and similar. I then tried webchat who redirected me back to Contact Centre. He did say the service did exist but need to call contact centre to implement. I cannot find any details on it when I researched other than Voice ID exists. Can someone point me in the right direction and / or verify it exists and what steps are needed? Many thanks

It's news to me if the service centres use voice recognition! The nearest they get is a dedicated password for use only when calling or chatting live online.
