Is giving me the error of " in\_array() expects parameter 2 to be array, bool given", the reason is that the function class\_implements() is giving me an error with the class passed as argument and is returning false instead of an array.  
It happens with the two-factor authentication, when is trying to see if that class implements an interface, but the class\_implements() function doesn’t find the class passed as argument, is there a way to disable two-factor authentication?

A full stacktrace of your error would be usefull for us to provide you better help because the error `in_array() expects parameter 2 to be array, bool given` can’t be associated with a specific problem.

Can you explain

- what you already did?
- what versions you are using?
- what did you change so its not working anymore (if it worked before)?

I installed cakedc users in my site, it gives me the error when I try to login with superuser, I am using cakedc users 9.  
This is the screenshot of the error in the site:

if you copied the `users.php` from the the repository to your `config/users.php` then make sure you are on the correct version of that file.

Especially that line is needed because this is was causing your error.

I added the Webauthn2fa in cakedc/users/config/users.php, but now is trying to enter the site from the Authentication plugin, not the cakedc users, and is giving me an exception of “Call to a member function getResult() on null”.  
What do I have to change so that it logins with cakedc users and not Authentication plugin?  
This is the screenshot:

You definitely should not edit any files present in `vendor` so if it wasn’t present in there you are not on CakeDC/Users version 9.3

Make sure you are on the latest version via `composer update -W`

Your error above means that the Authentication Component hasn’t been loaded.  
Did you add

```auto
public function initialize(): void {
    $this->loadComponent('CakeDC/Users.Setup');
}

```

in your `src/Controller/AppController.php`?

Thank you now is working.  
How can I get the getresult()-\>isvalid() with cakedc users?

</div>

Since you now have access to the AuthenticationComponent inside your controllers just use

```auto
$this->Authentication->getResult()->isValid();

```
