If your phone number has changed or the mobile device you use for authentication is lost, you will need to disable multifactor authentication for the LastPass Authenticator. To do so, you can use SMS account recovery to log in to your account and disable authentication. When you install Last Pass on the new phone, it request that you authenticate using 2FA. Unfortunately, the authenticator on your new phone won't be active until you log into last pass, so you would need to authenticate using the old phone that you no longer have. The safest solution would be to enable the Grid in Multifactor authentication.
- LastPass Authenticator Cloud Backup. Cloud Backup is a new feature of LastPass' Authenticator application for Android and iOS. It allows you to back up all authentication tokens in the cloud for easy recovery if you have to restore your mobile device or switch to a new device entirely.
- I use lastpass with 2fa (google auth), and I just got a new phone. Now on the new phone, I put my email address on the lock screen so should I lose my phone, people will know who to contact. However, this got me thinking, if I actually did lose my phone, and wanted to log into my email, my email password is stored on lastpass.
