Amazon Bedrock adds OBO token exchange for multi-tenant AI agents

By PulseAugur Editorial · [2 sources] ·

Amazon Bedrock AgentCore Gateway now supports on-behalf-of (OBO) token exchange, a feature based on RFC 8693 OAuth 2.0 Token Exchange. This enables multi-tenant AI agents to securely call downstream APIs while preserving the original user's identity and enforcing cryptographic least privilege. The implementation prevents the 'confused deputy' problem by issuing new, audience-bound tokens for each specific downstream service, ensuring that a token for one tenant cannot be used at another. AI

IMPACT Enhances security and identity management for multi-tenant AI agents, enabling more robust and auditable interactions with downstream services.

RANK_REASON This is a product feature update for an existing AWS service, not a new frontier model release or significant industry-wide event.
