Changing an Old Password to a Generated One

If you stored login details that you created before you began using LastPass, we recommend that you run the LastPass Security Challenge to identify potentially weak passwords. Once identified, you may want to change your old password to one randomly generated by LastPass.

You may also like to periodically update your passwords; LastPass tries to make this process as simple as possible for sites that you have stored in your Vault.

Replacing Your Old Password

We’ll use a demo Gmail account to show how to update a stored site with a new, generated password from LastPass.

To begin, log in to the target site and access the account settings or preferences page where you can change your password.

When you launch the ‘Change password’ page, you will usually be asked to enter your old password, with a new password entered twice. ¬†Click on the field icon in the current password field, and select the login. LastPass will fill in the current password for the login you selected:

pwchg3Select the options you wish, and if you accept the password that has been generated, click ‘Use Password’ to¬†autofill both the ‘New password’ and ‘Confirm new password’ fields. You will then see this confirmation to ‘Yes, Use for this Site’. Clicking, ‘No, Save as New Entry’ will just save this as a new entry in your Vault and not continue with the password change.

Now click ‘Save’ to submit the changes to the website. After clicking Save, LastPass will prompt you to either ‘Confirm’ or ‘Save New Site’:

By clicking on Confirm, you will tell LastPass to swap the old password for the entry with the new, generated password. Save New Site creates an entirely new entry for the site with your previous username and new, generated password.

If you choose not to confirm or save as a new site, the generated password will have its own entry in your Vault.

The next time you log in to your site, LastPass will autofill with the new, generated password!

If LastPass does not recognize the change in password when you submit it, you can simply:

  • Sign out of the site
  • Go to the login page for the site
  • Use LastPass to enter your username
  • Copy/paste the password from the ‘Generated Password’ entry that was stored when you accepted the new password
  • Click login

You will then be prompted by LastPass to accept the changes to the site’s entry, and now the new password will be stored with the entry in your Vault.
