The Google Authenticator app on my iPhone seems to be crashing. I tried rebooting a few times but no dice. I guess deleting and reinstalling the app will lose all my tokens; I have recovery codes religiously preserved, but setting up more than a dozen accounts all over again is going to be painful.
Has anyone had this problem before? Is there any way to extract the current data from the app? Even just a list of the accounts, so I know what to set up again.
I have a feeling my next TOTP generator won’t be Google’s.
I think by design they tend to make it very difficult to extract data from it, and on an iOS device it's going to be even harder, because your options are limited. ...Maybe... from iTunes you could back up your iPhone to a PC and then dig into it?
One of the backup strategies I'd advocate for for 2FA in the future: Print out the QR code you scan when you add 2FA to an account, and store it physically in a locked/secure place. When I get a new phone, all I have to do, is scan each sheet in the stack into my TOTP app, and I'm good to go: The QR codes contain the actual token used to generate your 2FA codes. And storing them offline makes them difficult to compromise!
