AI Agent API Authentication: OAuth vs API Keys and Service Identity
Choosing authentication for an agent is different from choosing authentication for a normal backend integration.
AI Agent Token Exchange: How to Issue Scoped Credentials to Agents
Agents often need temporary access to downstream systems without receiving a user's permanent credential.
AI Agent Session Binding: Preventing Stolen Tokens From Being Reused
A valid token can still be dangerous if it can be replayed from an unrelated workflow or environment.
AI Agent Refresh Tokens: How to Handle Long-Running Workflows Securely
Long-running agents need access after short-lived access tokens expire, but permanent credentials create unnecessary risk.
OAuth vs API Keys for AI Agents: Which Should Developers Use?
A practical comparison of API keys, OAuth, and service identities for AI agents.
AI Agent Delegated Identity: How to Act on Behalf of a User Safely
An agent may perform an action for a human, but the audit trail should preserve both identities.
AI Agent Credential Rotation: How to Change Secrets Without Breaking Workflows
Credentials eventually need rotation, but rotating them carelessly can interrupt production agents.
AI Agent Session Replay: How to Debug Multi-Step Agent Runs
Multi-step agent failures are difficult to reproduce because the final error often hides the earlier decision that caused it.
AI Coding Agent Secret Protection: How to Stop Credential Leaks
Agents can read files, logs, environment variables, and command output where secrets may appear.
AI Agent Authentication Failures: How to Recover Without Infinite Retries
Expired tokens, revoked grants, and provider authentication failures require different recovery paths.
AI Agent Memory Explained: Context, Sessions and Long-Running Tasks
Memory is not one database. Separate run context, session state, durable facts, and long-term recall.
How AI Agent Sessions and State Work in Production
A production agent needs separate ownership for request context, run state, sessions, durable business data, approvals, and audit events.
AI Agent Step-Up Authentication: When Actions Need Extra Verification
Not every agent action deserves the same authentication strength.
AI Agent Secret Management: Keeping Credentials Out of Context
An agent should never need to see a production secret just because it can call an API.
AI Agent Identity: Why Every Agent Needs a Distinct Security Principal
An agent should not operate as an anonymous extension of the user or as a shared service account. Give automated actors explicit identity and scoped authority.
AI Agent Service Accounts: Designing Machine Identities for Agents
Shared service accounts make attribution and permission management difficult.
