AI agent authentication is the process of verifying the identity of autonomous AI systems. Unlike human authentication (passwords), agent auth uses cryptographic methods like wallet signatures to prove identity without shared secrets.
As AI agents act autonomously, they need verifiable identity to access resources, interact with services, and establish trust with other systems.
API keys are static secrets that can leak. Wallet-based auth uses dynamic signatures — the private key never leaves the agent, and each authentication is unique.
GitHat issues 2-minute access tokens to agents. Short TTL limits exposure. Agents re-authenticate by signing a new challenge when the token expires.
