Google has finally released v2.0 of its Authenticator app for iOS today, but it seems many users are being caught by the update apparently deleting their saved tokens. I haven't tried this myself yet so I can't confirm, but as many of you are (hopefully) using two-factor authentication on various services, please make sure you aren't locked out of your accounts!

(And reminder: If you still don't use two-factor authentication wherever provided, please do! Of course, not all of them require a smartphone app, and other apps like Authy also support the same OATH/TOTP protocol that most configurations use.)
