There are different scenarios in which your 2FA may be inaccessible. Please read on for help with each case.
NEW PHONE (YOU ALREADY HAVE AN AUTHY ACCOUNT)
Delete your Authy app on your phone and visit https://www.authy.com/install to reinstall the Authy app. This will only work if you allowed multi-device login in your Authy account.
If you disabled multi-device login in your Authy account, you’ll need to completely reset your Authy account at https://www.authy.com/phones/reset.
Once installed, the Authy app will prompt you to enter your phone number (the same number registered with your Gemini account). Authy will send you an SMS text message with a code to enter into the Authy app and the Gemini token should re-appear shortly.
NEW PHONE NUMBER
Regardless of whether you have the Authy app installed, you must first update your phone number on the Authy website here. Please note, Authy can take up to 48 hours to fully reflect your phone number change.
After Authy confirms with you that your phone number has changed, please confirm with your new number with us by submitting a request here.
