Mobile Authentication Testing, From First Factor to Step-Up Verification
Validate every login, multi-factor, and step-up flow across all devices, languages, and regions to uncover logic flaws, prevent bypasses, and ensure secure, seamless authentication for every user.
Comprehensive Authentication Modeling
Ostorlab tests your full authentication surface — login, registration, password reset, MFA enrollment, and step-up challenges. Every flow is simulated like a real user, revealing bypasses and logic flaws that checklist testing misses.
Multi-Factor Support Across All Formats
Validate various second-factor mechanisms to ensure reliability:
- SMS OTPs
- TOTP apps
- Email codes
- Push approvals
- Third-party authenticators
Global and Multilingual Validation
Test authentication flows across different environments to catch inconsistencies:
- Regional differences
- Localization issues
- International SMS delivery
- Carrier-specific behaviors
Complex Authentication Made Simple
Express advanced rules and ensure correct behavior:
- Step-up triggers
- Risk-based flows
- Device binding
- Custom headers
- Session dependencies
Session and Token Lifecycle Testing
Verify all stages of session and token handling:
- Login and logout flows
- Token refresh
- Timeouts
- Device-switch events
- MFA enforcement
Developer-Ready Findings and Retesting
Every issue comes with clear guidance: what happened, why it matters, and how to fix it. Retest after fixes to confirm resolution and prevent regressions.
Ostorlab’s Authentication Testing Features
Flow-First Testing, Not Checkbox Testing
Focus on how users authenticate in real scenarios — and how attackers attempt to manipulate MFA and step-up flows.
Global-Ready Validation
Test authentication logic across languages, regions, and telecom environments to ensure consistent security worldwide.
Built for Modern Auth Architectures
Validate SMS, TOTP, email, push, third-party authenticators, custom headers, and advanced step-up logic — all within one testing framework.
Clear Ownership Handoff
Findings are structured so mobile and backend teams can quickly identify responsibility boundaries and implement fixes efficiently.
