Did we solve AI agent identity in 2025?

As 2025 comes to a close, I’m reflecting on how AI agents actually behaved in production systems this year.

Agents became more autonomous, more ephemeral, and more capable of acting across systems and delegating work. But identity still often felt bolted on using user or service account models.

Curious how others see it in hindsight: - Did anyone land on an agent identity model that worked well at scale? - Was this ultimately an IAM problem, or something that needs a new abstraction? - If it remains unresolved, what do you think breaks first?

No wrong answers.
