When you set up 2FA, you'll be given a number of emergency tokens. You can use one of these if you can't use your smartphone (eg: if it gets broken, stolen or sold). ''You only get shown these tokens when you sign up and never again'', so make a copy of them by selecting/pasting them from your browser and storing them offline (paper printout or memory stick) in a safe place. If you don't keep these tokens and also have a problem using your authentication device, you '''will be locked out of your account'''!
:These can only be used one time ever each and it may taketakes two of them to turn off 2FA (the first to log on without 2FA, and the second to shut off 2FA after logging in).
* You still need to follow [[Wikipedia:SECURITY|good security practices]]. Don't use your name, date of birth or anything obvious as a password that can be guessed in a simple [[dictionary attack]], don't write your password down in a place anyone else can see it, and consider whether or not it's a good idea to log into public terminals including schools, libraries and airports.
