I hadn’t run your code, but my educated guess is that the fault in your code flow is that nonces are user specific. While anonymous nonce is possible, it is useless for its purpose because it would be same for all anonymous users. So there is likely mismatch somewhere and you are trying to use … Read more
I don’t think there is a link that you can use to do it but there is some PHP. I personally like the following tidbit of code to add it. <?php add_filter(‘wp_nav_menu_items’, ‘add_login_logout_link’, 10, 2); function add_login_logout_link($items, $args) { ob_start(); wp_loginout(‘index.php’); $loginoutlink = ob_get_contents(); ob_end_clean(); $items .= ‘<li>’. $loginoutlink .'</li>’; return $items; } ?> You … Read more
There are 5 options 1) Ask The Client You haven’t been given what you need to do your work, so you should request it rather than hacking in to the clients site. This would be the Professional and ethical thing to do 2) Reset Password link Using the standard password reset link should do the … Read more
Failing to authenticate should do the trick for all the kinds of possible authentication – login form, xmlrpc, ajax, whatever Edit: actually realized there is a way to save sending the user related query to the DB function wpse208677_authenticate($user,$username,$pass) { remove_filter(‘authenticate’,’wp_authenticate_username_password’,20,3); return null; // if you want to whitelist your ip check for it and … Read more

You want to hook into wp_authenticate_user which will fire after WP has tried to authenticate the user but before logging the user in. You’ll receive either a WP_User object or a WP_Error object and you should return either a … Read more
If using Windows Authentication with IIS PHP can read the current authenticated user thats logged on from $_SERVER[“LOGON_USER”]; If this is set and the user is not getting a HTTP auth prompt you can assume the user credentials are correct. So with some WP coding you could read that $_SERVER[‘LOGON_USER’] and if not logged into … Read more
jquery Validation plugin should do what you want.
There are ways to trick WP into pre-populating the username field, but I’m pretty sure it would involve using POST and also tricking it into thinking there were errors in a previous submission. My advice would be to just use Javascript (or jQuery, as I’ve done below). It’s still ‘hacky’, but at least it gets … Read more
You do not specify a plugin you are using. But if a user login with a OAuth (used by the mosts social plattforms), then he cannot be logged in in WordPress. Why? A user needs a username and password to login. OAuth (and other methods) do not provide a password. They only answers with Yes, … Read more
Your problem probably starts with your callback: public function handleAjax( $action ) To send a JSON error or success, you just have to call wp_send_json_success( array( /* Data */ ) ); wp_send_json_error( array( /* Data */ ) ); The response will be like: { success : true, data : [ // Some data as key/value … Read more
