Provide a managed testing operation that runs each client's critical authentication journeys on a defined matrix of real phones, tablets, operating systems, account states, and identity methods. Specialists reproduce failures, preserve screen recordings and diagnostic evidence, and deliver developer-ready defect reports with release comparisons. The first version can be fulfilled manually with device testing and scripted checklists, then productized with reusable test runners and scheduled monitoring.

Authentication increasingly crosses mobile apps, embedded browsers, email links, identity providers, and backend account systems, creating failure modes that component-level monitoring does not expose. The signals span multiple industries and years, indicating a durable release-quality problem rather than one transient regression.
