Working definition
Authentication establishes who a user is; authorization decides which actions and records that user may access.
In a project brief, use this term to identify a concrete responsibility or observable behavior. Avoid treating vocabulary as proof that an implementation is complete. Product publishers can use similar labels for different workflows, so connect the term to the actual files, environment, people, and data involved.
Test with more than one account
A login screen alone does not protect records. Create controlled accounts and verify that one cannot access another’s private data. Test unauthenticated access and restricted administrative actions at the backend boundary, not only by checking whether buttons are visible.
Write one acceptance check that another person can repeat. Record the input, expected behavior, actual result, and environment. A useful check should fail visibly if the requirement is not met. These are editorial evaluation suggestions, not results from a cross-tool benchmark performed by this publication.
Use the definition in a real decision
Read the connected guide and relevant tool profile before committing to a platform. Verify current capabilities and plan requirements in the official documentation. If a requirement affects personal data, money, or a business-critical process, have an appropriate technical reviewer inspect it.
This Macaly-operated reference distinguishes definitions from product claims. Its featured recommendation is affiliated editorial opinion, not an independent certification. The goal is to make the brief and handoff more precise, not to imply that knowing a term removes engineering responsibility.
