I was assisting a man at the public library who was unable to login to his gmail account. He typed in his password and was prompted for a phone number, presumably so a code to be sent which would then have to entered in order to proceed with the login.
He said he had no phone and that he borrowed someone else's phone when he setup the account whatever that means. Anyway he kindly asked if I he could borrow the use of my phone number for this one-time purpose of logging in. I said no.
Would it have worked if I agreed and would there have been any implications?
