A developer signs in to an internal dashboard. A coding agent runs on the same laptop. If the agent can reach the browser session, a credential gateway may see its request as the developer's.
The important boundary is the exchange between a human session and a cloud role. A gateway can issue short-lived credentials for cloud operations, so the security decision needs to consider both the identity requesting access and the authority being issued.
A session is not a cloud role
A browser cookie carries an authenticated session. A cloud credential carries permissions to specific services and resources. A gateway sits between them: it evaluates the caller and decides whether to issue a credential.
If an agent can reuse a developer's session, the gateway may be unable to distinguish an agent request from the developer's own request. Short credential lifetime helps limit exposure, but it does not reduce the permissions granted during that lifetime.
Make the exchange accountable
- Give the agent its own identity and an approved way to request the role needed for its task.
- Bind credential requests to an audience, permitted actions, resources and expiration.
- Require independent approval for destructive operations or privileged roles.
- Keep browser profiles outside the agent's accessible workspace and protect the gateway from direct session reuse.
- Log who requested the credential, which role was issued and which cloud actions followed. Keep the credential value out of the log.
A practical check
Trace one ordinary deployment from agent request to cloud API. Can the gateway identify the agent? Can a read-only deployment task obtain permission to delete resources? Can security correlate the issued role with the action taken?
The answer to those questions determines whether a browser session is a convenient login or an unintended bridge to cloud administration.
