How to use the post_password_required() function in WordPress

The post password required() function in WordPress is an essential tool for content creators who wish to restrict access to their posts or pages, making them readable by only those who have the necessary password. This function may be used to make posts or pages password-protected. It is the responsibility of this function to ascertain whether or not a particular post has a password requirement and whether or not the user has already supplied the right password.


The function takes one optional parameter, $post, which is a WP_Post object. If $post is not provided, the global $post will be used.



The function will return a boolean value, which will either be true or false, to indicate whether or not a password is required for the post and whether or not the right password was supplied.

Function Logic

The post_password_required() function performs the following checks:

  • If the post does not have a password, the function returns false, indicating that no password is required.
  • If the post has a password, the function checks if the user has previously entered the correct password. This information is stored in a cookie on the user’s browser. If the cookie contains the correct password, the function returns false, as the user has already provided the correct password and does not need to enter it again.
  • If the post has a password and the user has not yet provided the correct password (or the cookie is not present), the function returns true, indicating that the post requires a password.


The function is very simple to use, as an example boilerplate:

if ( post_password_required() ) {
    echo 'This post is password protected.';
} else {
    echo 'This post is not password protected.';

By default, the_content() is already protected by this function, but it’s extremely useful for applying that same protection to anything outside the_content(). Typically, this might be custom fields that you’ve created (using Advanced Custom Fields) for example:

if ( post_password_required() ) {
    $value = get_field( "text_field" );

    if( $value ) {
        echo $value;
} else {
    echo 'You need to enter a password to see this information';
