Login user using wp_signon and WP_User object

Question

The problem is that wp_signon function requires password as plain text. Where WP_User object returns user password as hashed.

There is any way to safety login using user WP_User object? Something like this:

$user = new WP_User(1);

wp_signon([
    'user_login' => $user->user_login,
    'user_password' => $user->user_pass,
    'remember' => true,
]);

Answer 1

You need wp_set_auth_cookie:

wp_set_auth_cookie( $user_id, ( bool ) $remember );
