Authentication Is a Product Foundation
Authentication affects onboarding, security, data access, support, and trust. A Spring Boot backend should treat login, token refresh, password reset, and authorization as first-class product workflows.
Design Token Flows Carefully
Mobile and web clients often need different token storage and refresh strategies. Backend APIs should keep token lifetimes, refresh behavior, and invalidation rules explicit and easy to reason about.
Plan Authorization Early
Role and permission models become harder to retrofit after launch. OpenStair designs backend systems with clear ownership rules so APIs expose only the data a user should access.
