Use 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.

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.

Set up and configure

  1. Log in to LastPass and access your Vault by doing either of the following:
    • In your web browser toolbar, click the LastPass icon LastPass then click Open My Vault.
    • Go to https://lastpass.com/?ac=1 and log in with your username and Master Password.
  2. Select Account Settings in the left navigation.
  3. Click on the Multifactor Options tab.

  6. For the "Permit Offline Access" option, use the drop-down menu to choose from the following:
    • Select Allow if you wish to allow access to Grid even when you are offline. This will store an encrypted Vault locally so you can log in without using Multifactor Authentication in case of a connectivity issue.
    • Select Disallow to prevent offline access, which requires the use of Multifactor Authentication and to be connected to the internet when using Grid Multifactor Authentication.

      If this option is selected and you are not connected to the internet and/or https://lastpass.com is not available, you will be unable to access your Vault. Learn more about offline access.

    • Select Allow if you want iPhone 6 or older devices running using Grid authentication.
    • Select Disallow to prevent iPhone 6 or older devices from using Grid authentication.
