CodeIgniter 4 - Shield - Change password

Hi,
In my project i've started writing a change password functionality for the users, this is checked by confirming the current password.
Reading through the documentation i'm unable to find what method/helper I can use to run the current password check against the user.
Using the login example does not work, it throws an exception about the session already being active, so i have no clue what to use at this point.

Can someone push me in the right direction?


EDIT:
Did not look at all possible options, you can use the check() method to do that.
See: https://codeigniter4.github.io/shield/au...uth-helper

Another way is to use magic-link. In this method, the user uses magic-link to login and after logging in, it is checked that it is done by logging in through magic-link and it is used to change the password.
It is possible to use session or events in this method.(magicLogin)

Thank you for the suggestion, but the check actually does everything i've needed for this part.
I've written a custom validation rules 'old_password' that will check the current password for the user.

If anyone is interested on how this is done:

PHP Code:

public function old_password(string $password, ?string &$error = null): bool
{
    $result = auth()->check([
        'email'    => auth()->user()->email,
        'password' => $password,
    ]);

    if( !$result->isOK() ) {
        // Send back the error message
        $error = lang('Auth.errorOldPassword');

        return false;
    }

    return true;
}
