When you’re switching phones after an upgrade or an accident, the job of checking up on your two-factor verification apps can get lost in the hustle of transferring photos, contacts, messages, and all the other stuff that more quickly comes to mind. Without your security codes, though, you might get locked out of your key online accounts—here’s how to make sure that doesn’t happen.
Virtually every app and account of note now has two-factor enabled—that’s undoubtedly for the best, but it does place a lot of importance on your phone. You should always make sure your backup access methods are secure and current as well, just in case: with Facebook, for example, that might mean identifying some trusted contacts who can help you get back into your account.
If you use codes sent over SMS, life is a bit easier, particularly if you’re keeping the same number: Your codes will turn up on your new phone as normal. SMSes can be intercepted though, so we’d recommend switching to app-generated codes if you can. If you use SMS codes and change your phone number, make sure the new one is registered with whatever apps or services it needs to be before you lose access to the old one.
