Change your master password
The master password to your LastPass account allows access to everything in your account: all of your site passwords, secure notes, form fill items, and more. There is no limit for character length of the master password, but it is recommended that you use at least 12 characters and make sure it is memorable.
- 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.
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.
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.
