A User entity that requires a minimum-length password at registration but should simply ignore an empty password field during a later profile update puts many teams in front of the same question: does this need two separate entity classes, or is a single set of constraints with a bit of extra logic enough.

This article walks through both tools using a continuous registration and profile-update example.

Single sign-on through an external identity provider takes more than redirecting a login button. This guide shows how OAuth2 and OpenID Connect are integrated cleanly into Symfony, from the authorization code flow through ID token validation to role mapping into your own user management.

An OpenAPI specification that exists only for documentation does not get you very far. Anyone who treats it as a binding contract between frontend, backend and external consumers, and hardens it with contract tests, RFC 7807 error formats, security schemas and automated tooling, turns a YAML file into a genuinely productive quality tool.
