How do I update site passwords using Auto Change?

Auto Change is a feature that allows you to change a site’s password with a single click.

This feature currently supports some of the most popular websites available, but experience may vary. It is available on Chrome, Safari, and Firefox for users running LastPass v3.1.7 or later.

Is Auto Change secure?

Auto Change is a feature that was created with security as a top priority. Although LastPass is changing the password for you, the changes occur locally on your machine. Just like all other data on your account, the password change that occurs is encrypted locally before syncing, which ensures that your data can never be accessed by LastPass.

How to Use Auto Change

  1. Log in to LastPass and access your vault by doing either of the following:
    • In your web browser toolbar, click the LastPass icon active LastPass icon and select Open My Vault.
    • Go to and log in with your email address and master password.
  2. Locate your desired site password, then hover over it and click the Edit icon .
  3. In the Edit Password window, click Auto Change Password below the "Password" field.

    Note:  If you do not see this option, it is likely that the site does not support this feature, or you are using an unsupported web browser or version of LastPass. Learn how to check your LastPass version.

  4. Once a new web browser tab opens, click Change Password Now. LastPass displays a progress bar while opening another web browser tab (do not close out of this tab) and the following actions will happen automatically:
    • You are logged in to your selected site with your current password.
    • A new secure password is generated for your site via LastPass.
    • LastPass updates your password for both your site settings and within your LastPass vault.
  5. When the changes are complete, LastPass will automatically close the additional web browser tab for the site.
  6. Click OK on the confirmation message.
LastPass will now sync your updated password on all of your devices.
