My Passkey will not work.
Can I reset my passkey.
My part of the passkey was deleted and so passkey will no longer function, making logging in to virginmedia or O2 a hassle.
How can I reset it?
The VM help page below suggests de-registering and re-registering the device
https://www.virginmedia.com/help/account/what-is-device-authentication
but VM has been attempting to launch a single sign-on for VM O2 this week (which has not exactly gone smoothly for some unlucky customers) so expect the possibility of some VM 'confusion' when you try to make changes.
