Alex is right, This app is very secure if you can't get in, but there should be a way to get in if it's your account. Been trying for months to recover my old accounts, as soon as I click the button to skip verifying with this app it says it cannot verify the account was mine. I DONT HAVE THAT INFORMATION. I lost it when my old phone broke down. There is literally no way for me to recover my accounts. This is a HUGE fault on Google. The authenticator should not be the only way to verify.
