T-Mobile has a new feature where you have an [edit:] 6-12 digit pin associated with the account, and it's used in the store or when porting a number. When activating the pin (which requires calling them), they used an SMS text message to verify me. I asked if people can change the pin like I just did, he said that they'd always be sent a text message. I hope that's true, because if so that'd mean a hacker would need my phone. I think that guards against the attack whereby someone steals your number by porting it to another provider. Assuming what T-Mobile is saying is true. I also use Google Authenticator, but that terrifies me since someone could steal my phone or I could lose it, and I'd have to find (and I'd better re-create NOW) printouts of all the words to recover / move Google Authenticator access tokens.
