wp_set_password( string $password, int $user_id )

Updates the user’s password with a new encrypted one.


For integration with other applications, this function can be overwritten to instead use the other package password checking algorithm.

Please note: This function should be used sparingly and is really only meant for single-time application. Leveraging this improperly in a plugin or theme could result in an endless loop of password resets if precautions are not taken to ensure it does not execute on every page load.

    Please note: This code should be deleted after ONE page load, otherwise the password will be reset on every subsequent load, sending the user back to the login screen each time.
