Thank you @chalasr. |
|
Thanks for merging. Will run my test suite somewhen in the next days once I find time for it. I'm relatively confident that this is fixing the issue with 2fa-bundle on Symfony 5.4 👍 |

Confirmed. 2fa-bundle is all green on the latest 5.4.x-dev, both old security system and authenticator-based system 👍 |

That's great news! |

In #42050, we moved the
hasUserChanged()logic used for deauthentication from AbstractToken to ContextListener.Problem is that this check is now done against on all kind of tokens, whereas it was only for
AbstractTokeninstances before.That breaks https://github.com/scheb/2fa, tokens get wrongly deauthenticated in the middle of the 2fa auth process.
This fixes it by skipping non-AbstractToken implementations.
We may want to provide a way to opt-in/out the
hasUserChanged()logic on a custom token with e.g. a marker interface, but that's not necessarily worth it for now IMHO.
