Step #1: Enable the LastPass Authenticator app in your LastPass vault

You can configure your LastPass account to use the LastPass Authenticator app for multifactor authentication when you log in and access your LastPass vault.

Important: If you are setting up passwordless login for your vault, you must disable all other multifactor options for your account except for the LastPass Authenticator app.

Log in to LastPass and access your vault by doing either of the following:
- In your web browser toolbar, click the LastPass icon and select Vault or Open My Vault.
- Go to https://lastpass.com/?ac=1 and log in with your email address and master password.
Select Account Settings in the left navigation.
Select the Multifactor Options tab.
Select the Edit icon for the LastPass Authenticator.
For the Enabled drop-down menu, select Yes.
For the Permit Offline Access drop-down menu, choose one of the following:
- Select Allow if you want to allow access to LastPass 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 LastPass.
  Important: 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.
When finished, click Update.
Enter your master password, then click Continue.
When prompted, click Enroll.

Results: You have enabled the LastPass Authenticator app for multifactor authentication to protect your LastPass vault.
