Create custom login page:

1. To create a custom login page, click the Set up a Login Page button.
   
2. Choose a template.
3. Start designing your login page and make sure to save it.
   
4. To have the WordPress default login page redirect to your custom page activate the Redirect the Default Login Page setting:
   

   Note: If you use the Redirect the Default Login Page option under Page Settings of the login page, it should redirect all calls to the default login page which is located at: https://example.com/wp-login.php however it does not prevent it from being accessed as that default login page will still be used for password resets, login errors, logouts, and registration if that is enabled.

5. Lastly, activate your login page.
