Grid Multifactor Authentication

Grid Multifactor Authentication is an option for those who do not want to utilize mobile devices. With Grid Multifactor, you will print a sheet that is used to look up specific matching values when logging in to LastPass, and provide a code derived from your Grid to log in and access your account when prompted by LastPass.

Note: Feature availability may vary depending on your account type.

For LastPass admins, it is recommended that you complete the steps for enabling Multifactor Authentication in the Admin Console.

For LastPass users, it is required that you follow all steps in Enable Multifactor Authentication (Users) before proceeding.

Please note that if you have more than 1 Multifactor Authentication option enabled for your account, you must select your desired default authentication option from the drop-down menu at the bottom of your Multifactor Options window in order to be prompted to authenticate with your preferred option when logging in to LastPass.

Disable authentication for a lost grid

If you have misplaced your Grid or feel it has been compromised, you can click I've lost my grid on the Multifactor Authentication window. Once redirected, you can enter your LastPass email address and click Send Email to be sent an email with a set of instructions on how to disable Multifactor Authentication. If you do not receive an email, you may have a secondary security email enabled where the email was sent instead, and/or check your spam/junk email filters. If you are an Enterprise user, your account may have policies enforced that prevent disabling Multifactor Authentication via email. For these users, please contact your LastPass admin to disable it for you.
