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);

    'user_login' => $user->user_login,
    'user_password' => $user->user_pass,
    'remember' => true,

You need wp_set_auth_cookie:

wp_set_auth_cookie( $user_id, ( bool ) $remember );
  • It is safe? I don't see any password validation or hash parring. Basically it bypass all verification done in normal login. May 1, 2016 at 9:59

    Yes because there is nothing to verify - you already have the user ID that you want to log in, it's on you to make sure it's okay to do so. May 1, 2016 at 10:00
