Antonio Ortells

Antonio is a Senior Product Manager at Okta, where he leads the strategy for the "plumbing" of modern identity: sessions and refresh tokens in Auth0. Drawing on his previous experience as a Solution Architect and Technical Account Manager, Antonio brings a deep, customer-first perspective to building seamless and secure identity solutions. He spends his days obsessing over session protection and developer experience, ensuring that security remains invisible yet robust. When he isn't mitigating session-based risks, you’ll find him cheering at a football stadium or at home baking a newfound cake recipe.

I’m a Senior Developer Advocate at Auth0, and I like to work on various technologies. I’ve developed software for all sorts of platforms, from CD-ROM and the PalmPilot to my current area of focus, mobile phones, IoT devices, and AI. When I’m not looking for strange new platforms to write software for, I’m playing a strange old instrument — the accordion!
