Why it matters
Long-lived M2M tokens held by AI agents are a growing attack surface, and short-lived rotating credentials are a practical mitigation defenders can apply to limit the blast radius of a leaked agent key.
A Kinde-sponsored tutorial on DEV Community demonstrates why leaked AI-agent machine-to-machine (M2M) access tokens remain exploitable, contrasting a static agent that holds one long-lived token against a rotating agent that refreshes short-lived tokens before expiry using Kinde's client-credentials grant. The author builds both agents and attempts to replay stolen tokens to show that short token lifetimes plus rotation neutralize a captured credential within minutes.
