As AI agents become more autonomous, a critical security gap is emerging: standards haven't caught up to the technology. A post on LessWrong from someone working with Microsoft's identity team lays out the urgent need for standardized protocols governing how agents authenticate and receive permissions. The core problems: agents shouldn't hold secret keys—they should only act as delegates to services. And when permissions are granted, they need to be granular, time-bound, and adaptable to the agent's actual needs in the moment. Companies like Anthropic and Microsoft are developing solutions, but the field still lacks unified standards—like the OAuth protocols that transformed web security. Identity experts warn that rolling your own agent authentication is as risky today as it was for web developers two decades ago. The IETF is weighing in, but the race is on to standardize before everyone builds it differently.
