There used to be an easy way of doing this but it seems Google have removed it.
I don't want to mess anything up as I have a number of accounts which use 2FA and I don't want to get locked out of them.
I don't mind starting from scratch and setting up each account with 2FA, but I don't know what the best way of doing this is.
Can anyone give me a step by step guide?
If I do start from scratch, I've read about a new Authenticator app called 'Authy' which I might start using, which seems to work better than 'Google Authenticator'.
