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.
Note: In order to revert your Master Password, you had to have logged in to the LastPass web browser extension at least once since your account was created.

Suppose you changed your Master Password on April 1, 2020, but on April 15, 2020, you have forgotten your Master Password and you need to revert back to the April 1 st Master Password. If you do this, any changes you made to your Vault since April 1 st are lost; your Vault is restored to exactly how it looked on April 1 st right before the Master Password change.

To revert to your previous Master Password, do the following:
  1. Navigate to
  2. 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.
  3. 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.

  4. To proceed, click the link to revert to your previous Master Password. If prompted again, click OK.
  5. A  message indicates that your most recent Master Password change has been reverted.
You have successfully reverted to your previous Master Password, and can log in to LastPass using it.
What to do next: (Recommended)

It is strongly recommended that you perform the following steps immediately after updating your Master Password in order to create new Recovery One Time Passwords:

  1. Log out of LastPass on every computer and/or mobile device where you have installed LastPass and accessed your LastPass Vault. You can check your active sessions for all devices.
  2. Log back in with your new Master Password.
For each computer and/or device where this is done, a new Recovery One Time Password is created, which can be used for account recovery if your Master Password is ever forgotten.

What to do next: If you logged in to your online web Vault (i.e., the LastPass website) on a public or untrusted device, it is strongly recommended that you 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: (Optional)

If you have created a list of temporary One-Time Passwords to use on public/untrusted computers, then please be aware that changing or resetting your Master Password will invalidate all one-time passwords that you generated before the change occurred (as it requires your Vault to be re-encrypted). This means that you will need to generate new OTPs after a Master Password change, as all OTPs you generated previously will no longer be listed. Learn how to generate new one-time passwords.
