The following code can be used to automatically redirect users after they’ve reset their password.
This code will automatically redirect them to the home page.
function itsg_after_password_reset_redirect() { wp_redirect( home_url() ); exit; // always exit after wp_redirect } add_action('after_password_reset', 'itsg_after_password_reset_redirect');
Note:
I highly recommend any customisations are placed into a custom plugin (NOT your theme’s functions.php file) – this way you can easily enable/disable the customisations and keep them when you update or replace your theme.
See How to create a WordPress plugin for your custom functions for how to do this.
