Change Your Master Password
The Master Password to your LastPass account allows access to everything in your account: all of your Sites, Form Fills, Secure Notes, 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 in to LastPass and access your Vault by doing either of the following:
- In your web browser toolbar, click the LastPass icon then click Open My Vault.
- Go to https://lastpass.com/?ac=1 and log in with your email address and Master Password.
- Select Account Settings in the left navigation.
- On the General tab under Login Credentials, click Change Master Password.
- Enter your current Master Password, then create a new Master Password and enter a password hint (recommended – this is a clue that is sent in a reminder email to help you remember your Master Password if it is ever forgotten). Tip: We recommend using the following best practices when creating your Master Password:
- Use a minimum of 12 characters, but the lengthier the better
- Use upper case, lower case, numeric, and special character values
- Make it pronounceable and memorable, but not easily guessed (e.g., a passphrase)
- Make sure that it is unique only to you
- Don't use personal information
- A good example is: Fidoate!my2woolsox
- Click Save Master Password.
Result: Your changes are saved, and you are logged out of LastPass.
- Log back in using your new Master Password.
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:
- Log out of LastPass on every computer and/or mobile device where you have installed and accessed your LastPass Vault. You can check your active sessions for all devices.
- Log back in with your new Master Password.
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.
