Authorization
Determines what an identity may do.
An everyday example
Verified identity still needs permission for each door.
- Present identityAuthentication
- Check access scopeAuthorization
- Enter permitted areaProtected resource
- Record key actionsAudit log
Credentials can have scopes and expiry. The card is not unlimited authority. Enforce access rules on the server.
Where this term is useful
These are related contexts, not prerequisites.
Back in the project
When it comes up: When signing in, sharing data, and configuring secrets.
What to do next: Verify server rejection with different identities; hiding buttons is insufficient.
Open the related method and stepsWhat can this analogy leave out?
Authentication differs from authorization; hidden buttons are not access control, and signing is not encryption.
Everyday examples explain roles and relationships; actual behavior follows the tool, language, or platform.
