    The reset_password() function in WordPress is designed for handling the process of resetting a user's password. Here's a detailed explanation of its functionality and parameters, along with a sample usage:

    Function:

    • Purpose: reset_password() is used to reset the password of a WordPress user. It's typically invoked as part of the password recovery or change process.
    • Process: When called, this function updates the user's password in the WordPress database.

    Parameters:

    1. $user (WP_User):

      • Type: WP_User object.
      • Description: This parameter is the user object for whom the password is being reset. It is not just the username or user ID; it's the full user object, which contains all the information about the user.
      • Required: Yes.
    2. $new_pass (string):

      • Type: String.
      • Description: This is the new password that you want to set for the user. It should be provided in plaintext (i.e., not hashed), as WordPress will handle the hashing process.
      • Required: Yes.

    Sample Usage:

    $user = get_user_by('email', 'user@example.com'); // Retrieve the user by email or username
    
    if ($user) {
        $new_password = 'newpassword123'; // The new password in plaintext
        reset_password($user, $new_password); // Reset the password
    
        // Optionally, send an email to the user notifying them about the password change
        wp_mail($user->user_email, 'Your Password Has Been Reset', 'Your new password is: ' . $new_password);
    }
    

    In this example:

    • We retrieve a user object using get_user_by(). You can retrieve the user by email, username, or other identifiers.
    • We define a new password in plaintext.
    • We call reset_password() with the user object and the new password.
    • Optionally, we send an email to the user to inform them about their new password. This step is not mandatory but is good practice for user communication.

    Remember, handling passwords in plaintext requires caution. Ensure that your code is secure and follows best practices to protect user data.
