# Authentication and Security

Validate secure access flows under real device conditions to ensure your application protects user data and handles identity verification reliably. The Authentication and Security section focuses on testing biometric authentication and device level passcode scenarios across iOS and Android devices.

Modern mobile apps rely heavily on biometric verification such as fingerprint and facial recognition, along with device passcodes, to secure sensitive workflows including login, payments, profile access, and confidential data views. These flows behave differently depending on platform level security settings and hardware capabilities. This section guides you through simulating biometric approvals, handling authentication failures, and validating passcode protected scenarios on real devices.

For enterprise teams, this ensures compliance readiness, stronger security validation, and confidence that critical authentication journeys work seamlessly before release.
