Using Google Authenticator to Login
After your LastPass account is registered within the Google Authenticator app, the next time you login to LastPass on an untrusted device, you will receive the Google Authentication dialog:
Go to your Google Authenticator App and input the current authentication code you see in the app into this dialog. If the code expires before you have a chance to authenticate, simply use the next code that appears in the app.
Logging in Offline
When multifactor authentication is enabled, you can choose whether to allow LastPass to store an encrypted vault locally so you can log in without an internet connection or not. If you enable offline access, you will be able to login without using Multifactor (with the exception of Yubikey) in case of a connectivity issue.
With some internet configurations (typically wireless connections and waking from sleep), LastPass may log in offline first before establishing connectivity to your online vault and prompting for your authenticator code. This may cause LastPass to AutoFill any login credentials you have saved in LastPass for the current page you are on. If you wish to disable offline access, you may do so in your account settings. In the vault, click Settings on the left navigation pane > Multifactor Options > Google Authenticator > Permit Offline Access: change it to Disallow and save the change. Note: you will need to clear LastPass local cache or re-log in online since the change so the local cache is automatically cleared.
