As AI agents become autonomous actors in software systems, traditional identity architectures built for human sessions break down. This piece argues that identity must move from a peripheral feature to a core architectural layer. Key topics include Non-Human Identity (NHI) management, Relationship-Based Access Control (ReBAC) as a replacement for coarse-grained RBAC, token downscoping for multi-hop agent chains, and automated lifecycle governance for AI service accounts. Industry-specific implications are covered for retail, fintech, healthcare, and B2B SaaS, with practical guidance on decoupling policy from code, solving the token exchange problem, and building for day-two operations like session revocation and audit trails.
