How do I revert to my previous master password?

Reverting your master password means that you are resetting it back to your previous master password, and in doing so, your LastPass vault will be restored exactly the way it was since the last master password change. This may result in data loss (i.e., any new items updated/added since the change will not be recovered).

Important: You can revert to your previous master password only if the change had taken place within the last 30 days.

Remember: In order to revert your master password, you had to have logged in to the LastPass browser extension at least once since your account was created.

Troubleshooting: Before proceeding with the recovery options below, please be sure you have temporarily disabled pop-up blockers; otherwise, you must allow pop-ups from the LastPass website when prompted in your web browser toolbar.

Example:

Suppose you changed your master password on April 1, 2021, but on April 15, 2021, you have forgotten your master password and you need to revert back to the April 1 master password. If you do this, any changes you made to your vault since April 1, 2021 are lost; your vault is restored to exactly how it looked on April 1, 2021 right before the master password change.

About this task: To revert to your previous master password, do the following:

Navigate to https://lastpass.com/revert.php.
Enter your email address, then click Send Email .
- If you have set up a security email address, check the inbox for that email address.
- If you did not set up a security email address, check the inbox for your LastPass account email address.
Click the link within the email from LastPass (valid for up to 2 hours).
Result: A new web browser window or tab opens that indicates the date of your last master password change.
To proceed, click the link to revert to your previous master password. If prompted again, click OK.
A message indicates that your most recent master password change has been reverted.

Results: You have successfully reverted to your previous master password, and can log in to LastPass using it.

What to do next: Create new Recovery One Time Passwords on trusted devices (strongly recommended)

Create new Recovery One Time Passwords for account recovery (in case your master password is ever forgotten) by doing the following:

Log out of LastPass on every trusted computer and/or mobile device where you have installed LastPass and accessed your LastPass vault. You can check your active sessions for all devices.
Log back in with your new master password.

What to do next: If you are using a public/untrusted computer (recommended)

Clear the browser cache on all web browsers where you accessed LastPass in order to clear the Recovery One Time Password that was created from accessing the LastPass website.

What to do next: If you use temporary, one-time passwords (optional)

Generate new temporary, one-time passwords because all OTPs you generated previously are now invalidated and no longer listed due to your vault being re-encrypted from your master password change.
