Most AI benchmarks test reasoning. Almost none test whether the agent can wire up authentication securely. 🧐 We built the @auth0 Agent Experience Score to actually measure it. Check it out! auth0.com/agent-experience

Fine-grained authorization for RAG is one of the most underestimated problems in production AI. If your agent can retrieve documents, it needs to enforce who's allowed to see them, not just at the role level. With @auth0 FGA and LlamaIndex Workflows, authorization is structural: baked into the retrieval step, not bolted on at the API layer. Great collaboration with @jerryjliu0 and the @llama_index team showing exactly how this works in production → auth0.com/blog/securing-ai-d…
One thing that keeps coming up when teams add AI to their stack: auth gets way more complicated than the standard "who is logged in" You start asking questions like ⚪️ who's agent did this? ⚪️ what docs can my agent go read? ⚪️ who do i blame when things go wrong? @itsclelia and @sambego wrote on fine-grained RAG pipelines so AI only sees what it's allowed to see worth a read if you're working on this problem: auth0.com/blog/securing-ai-d…

Broken Access Control tops 2025 OWASP lists for web apps and APIs. It persists despite modern tools. Why is it still so hard to fix? I have some thoughts: auth0.com/blog/why-broken-ac…

Policy-Based Access Control (#PBAC) is commonly considered an authorization model, but I disagree and explain why in this article published on the @idpro_org blog. What's your take on this? idpro.org/is-pbac-an-authori…
