Hey. I don't know what's better for you. I can also make a proposal PR if you like that more. I would rewrite the Authenticator stuff like that:

enum Suit: string
{
    case CLIENT_CREDENTIALS = 'client_credentials';
    case PASSWORD = 'password';
}

interface IAuthenticatorOptions {
}

class ResourceOwnerPasswordGrantAuthenticatorOptions implements IAuthenticatorOptions {
    public string $grandType = 'password';
    public function __construct(public string $clientId, public string $username, public string $password) {}
}

class ClientCredentialsAuthenticatorOptions implements IAuthenticatorOptions {
    public string $grandType = 'client_credentials';
    public function __construct(public string $clientId, public string $clientSecret) {}
}


class someAuthenticator {
    private function tokenRequestToForm(IAuthenticatorOptions $options): string
    {
        return match(true) {
            $options instanceof ResourceOwnerPasswordGrantAuthenticatorOptions => http_build_query([
                'client_id' => $options->clientId,
                'username' => $options->username ?? throw new InvalidArgumentException(),
                'password' => $options->password ?? throw new InvalidArgumentException(),
                'grant_type' => $options->grandType
            ]),
            $options instanceof ClientCredentialsAuthenticatorOptions => http_build_query([
                'client_id' => $options->clientId,
                'client_secret' => $options->clientSecret ?? throw new InvalidArgumentException(),
                'grant_type' => $options->grandType,
            ])
        };
    }
}

With that change you don't need the knowledge for what grandType does need what fields, because the classes are specific.

This PR is allot of work. Thank you for tackling it!

Since I find it to complicated to explain my proposal about the Authenticator stuff, I made a PR to your PR-Branch.

I also created a PR for my comments on the ForXXX Options.
