> @elchris any support for 5.3 with the new new Authenticator-based Security ? @MatthieuMan see #685 - it's based off of main, rather than this branch.

Still working on this. Adding an authenticator that manages authentication via the new `Passport` with user and credential badges.

Not sure about the user provider dependency injection yet, will be testing in the context of another app.

Token storage is already taken care of in `AuthenticatorManager::handleAuthenticationSuccess()` when `::executeAuthenticator()` is absolutely sure everything is kosher, so the token storage dependency in the `OAuthAuthenticator` was not needed.

Removing support of Symfony 5.1 and 5.2 as a result of ProxyManager dependency change for ClassGenerator.

Working on it [here](https://github.com/iisisrael/FOSOAuthServerBundle/tree/symfony-6-clean). Builds on #685. Trying to maintain BC support for Symfony 5.3, but that might be a lost cause. Branch / version management on this package could...

Forgot to mention, I've only worked on this in a linux environment. I'll boot into windows tomorrow and see what I see.
