Use any of these functions
Checks a user's login information and logs them in if it checks out.
<?php wp_login( $username, $password, $deprecated ); ?>
- (string) User's username
- (string) User's password
- (string) Not used
- False on login failure, true on successful check
Use the global $error to get the reason why the login failed. If the username is blank, no error will be set, so assume blank username on that case.
Plugins extending this function should also provide the global $error and set what the error is, so that those checking the global for why there was a failure can utilize it later.
