The LastPass autofill feature is one of its endearing attributes for users. This is because manually entering passwords and user IDs into different sites can be inconvenient.

However, some users are complaining that this all-important auto-fill feature is not working for some reason. If you also face this issue, this guide will show quick ways to restore normalcy to your password manager.

Why is my LastPass not auto-filling?

Below are some of the reasons LastPass might not be auto-filling on your browser:

  • Autofill is disabled: As simple as this may look, if LastPass is not auto-filling on Chrome, Firefox, or Edge, it might be because the feature is disabled. You need to log into the extension and enable autofill.
  • Issues with the extension: LastPass can sometimes malfunction, leading to this issue. In this case, you might need to recreate the password entry or switch to another password manager.

What can I do if LastPass autofill is not working?

1. Check that LastPass autofill is enabled

  1. Click the LastPass icon in your web browser toolbar.
  2. Select the Preferences option in the left pane.
  3. Now, select General.
  4. Finally, enable the setting Automatically Fill Login Information and click Save.

2. Use another password manager

Since the whole point of a password manager is to remember all passwords for you and autofill them in the right websites, you need a fast fix.

A good solution is to switch to a different password manager. We use RoboForm because of its excellent security features and unlimited password storage.

RoboForm already has smart imports from most password managers, including LastPass. This tool allows you to back up and sync your passwords across all your browser and devices.

The top-notch security is maintained by two-factor authentication, easy password access, and a powerful password generator.

RoboForm will help you generate unique and strong passwords instead of weak or reused password options.


Secure your digital activity and store your passwords and private data with RoboForm.

3. Recreate the site entry

  1. Access your LastPass vault.
  2. Click the Passwords option in the left pane.
  3. Now, hover over the entry you want to remove and click the Delete icon.
  4. Click the Yes button when prompted to confirm the action.
  5. Finally, recreate the entry by logging into the site again.

If the LastPass autofill feature is still not working, you might need to remove the site it is failing for and add it again.

4. Export LastPass autofill data and use the browser’s autofill

  1. Access your LastPass account.
  2. Select Advanced Options > Export in the left pane.
