Manage Trusted Devices for Multifactor Authentication
Multifactor Authentication is a security feature that can be enabled for protection against unauthorized access to your account. If you're using a personal computer that is only used by you, and you follow general security best practices (e.g., run anti-virus service, avoid clicking suspicious links, etc.), you can choose to "trust" your device, which skips the Multifactor Authentication prompt for 30 days.

Skip Multifactor Authentication for a specific device
To skip Multifactor Authentication from a specific device for 30 days but still have it running on other devices, do the following:
- Using the computer that you wish to exempt from Multifactor Authentication, click the LastPass icon in your browser window to log on. (If you are already logged on to LastPass, first log off.) Next, log on to log on to LastPass.
- The Multifactor Authentication window appears. Do the following:
- Enable the checkbox for the "Trust this computer for 30 days" option and provide a name for the computer. (If this window does not appear, you have not enabled Multifactor Authentication, or you have already exempted this computer).
- Open your mobile authentication app on your device, enter the code into the web browser window, then click Authenticate. This is the last time, for the next 30 days, you will need to provide Multifactor Authentication for this device.
Re-enable Multifactor Authentication on a specific device
If you set up Multifactor Authentication on your account but exempted a (specific) device from this requirement, you can re-enable Multifactor Authentication for that device by doing the following:
- Log in to LastPass and access your Vault.
- Click Account Settings in the left menu.
- Click the Trust Devices tab.
- In the "Label" column, locate your device (the default auto-generated name will be alphanumeric, unless you re-named it), then uncheck the box for "Enabled". When finished, close the Account Settings window.
