How do I regenerate a key for the Google Authenticator in LastPass?
You can regenerate a key for the Google Authenticator in order to set it up for your LastPass account again if you lost your mobile device, got a new device, or are concerned that the security of your existing key may have been compromised. Please note that this will require you to re-associate the Google Authenticator with your LastPass account, then re-enable the authenticator from the Multifactor Options in your LastPass Account Settings.
What to do next: You can set up the
Google Authenticator on your mobile device, then re-enable the Google Authenticator in your LastPass Multifactor Options.
