Separate authentication, data authorization, transactional messaging and runtime hosting.
Step-by-step workflow
01
Define data ownership
Write explicit resource ownership and admin roles, not just a login screen.
02
Choose identity layer
Compare managed identity against self-hosting based on compliance and team operations.
03
Enforce authorization on every API
Verify signed tokens correctly and check permissions against the resource being accessed.
04
Add transactional messaging
Use server-originated emails for invitations, verification and notifications.
05
Exercise abuse cases
Test rate limiting, replay, user enumeration, account deletion and restore.
Editorial note
Examples are starting points, not production security audits. Confirm dependencies, versions and pricing using linked vendor documentation.
