I lost my phone! How do I disable multifactor authentication for LastPass?

If your phone number has changed or the mobile device you used for authentication is lost, you should immediately disable multifactor authentication for your device (via email) so that you can log in and access your LastPass account.

Restriction: If you have a LastPass Teams or LastPass Business account, the ability to perform these actions may be limited or prohibited due to policies enabled by your LastPass admin.

Attention: The LastPass Authenticator app cannot be disabled via email. To access your account, you can use SMS account recovery to log in, then disable multifactor authentication for your device. If SMS recovery had not previously been set up, please contact LastPass Support by navigating directly to this article and selecting a contact option.

About this task: To disable multifactor authentication for supported authenticators, do the following:

Log in to LastPass with your email address and master password from your desktop or another device.
Click Additional Multifactor Options.
When prompted, click the I've lost my <authenticator app name> device hyperlink on the bottom of the window.
When prompted, enter your email address, then click Send Email.
An email is sent containing a link that will allow you to disable multifactor authentication. Check your inbox, then click the link within the email.

Note: 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.
Once clicked, a confirmation window appears informing you that multifactor authentication for LastPass has been disabled for your authenticator.

Results: You can now log in to LastPass with your email address and master password, and will not be prompted to authenticate.

What to do next: The following options are recommended once you have logged back in to LastPass:

If your device was lost or stolen, it is strongly recommended that you change your master password – learn how here.
You can re-enable multifactor authentication for a new device – learn how here.
