Authentication & Authorization Choices

Picking the wrong auth approach creates security holes or developer pain. You need to analyze flows (sessions, JWT), providers (OAuth 2.0, OIDC), and roles/permissions.

Starting points

• OAuth 2.0 overview
• OpenID Connect
• JWT intro

Key Points

• Do you need short‑lived tokens, refresh tokens, or sessions?
• How will you revoke/rotate tokens and manage scopes/roles?
• Are you storing secrets securely (vault, KMS)?
