Authentication vs Authorization
Separate proving identity from deciding which actions that identity may perform. Model permissions around business actions and test them with accounts from every role.
Authentication answers who is making a request; authorization answers whether that identity can perform the requested action. A signed-in user must still be checked for every protected resource. A reliable approach to authentication vs authorization begins with evidence, proportionate controls and a clear next step.
Put the issue in context
Separate proving identity from deciding which actions that identity may perform. The strongest choice is usually the one that remains supportable in everyday work.
A dependable approach
- Authenticate securely: Use approved sign-in, recovery and multi-factor patterns.
- Authorize server-side: Check ownership, role and context on every sensitive action.
- Default to denial: Grant only documented capabilities rather than trusting missing rules.
- Audit changes: Record important role, permission and account-administration events.
If the work touches a live service, agree who can approve the change and how it will be reversed. That discipline is usually faster than diagnosing several unrecorded changes later.
One risk to watch
Do not hide an admin button in the interface and assume the underlying API is protected.
The result to aim for
Model permissions around business actions and test them with accounts from every role.
