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 device that is only used by you, and you follow general security best practices (e.g., run anti-virus service, avoid accessing suspicious links, etc.), you can choose to "trust" your device, which skips the Multifactor Authentication prompt for 30 days. You can also revoke trust for a device so you are prompted for Multifactor Authentication again.
Trust a device (skip being prompted for Multifactor Authentication)
To skip Multifactor Authentication from a specific device for 30 days but still be prompted on other devices, do the following:
- Using the device for which you want to skip Multifactor Authentication prompts, log in to LastPass.
- When prompted by Multifactor Authentication, check the box to enable the Trust this <device> for 30 days option.
Note: If you are not prompted with this option, it means either you have not enabled Multifactor Authentication, or you have already set this device as trusted.
Revoke trust for a device (be prompted for Multifactor Authentication)
If you set up Multifactor Authentication on your account and trusted a device but now need to revoke that trust and be prompted again to authenticate using a multifactor authenticator, do the following:
- Log in to LastPass and access your Vault by doing either of the following:
- Go to https://lastpass.com/?ac=1 and log in with your username and Master Password.
- In your web browser toolbar, click the LastPass icon then click Open My Vault.
- Select Account Settings in the left navigation.
- 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.
