Authentication Testing, From First Factor to Protected Flows
Validate login, multi-factor and session handling, then test the protected features behind them to uncover logic flaws and bypasses before release. The same capability covers your web apps.
Comprehensive Authentication Modeling
Ostorlab signs in with the test credentials you provide and tests your authentication surface: login, 2FA steps, session handling and the protected features behind them. Flows are exercised like a real user, revealing bypasses and logic flaws that checklist testing misses.
Multi-Factor Support for Common Formats
Complete second-factor steps automatically once the test account is set up:
- SMS OTPs, via a dedicated test number from Ostorlab
- TOTP authenticator apps, via the shared seed
- Email codes, via a dedicated test mailbox
- Browser-based authentication flows
- Manual code entry for proprietary flows
Regional and Multilingual Apps
Test apps built for different markets:
- Apps listed only in specific countries
- Localized, non-English interfaces
- Market-specific login and onboarding screens
- Test numbers and mailboxes set up for your flows
Complex Authentication Made Simple
Handle non-standard authentication with the right tool:
- Client certificates (PEM)
- Appium scripts for custom schemes
- Custom HTTP headers and tokens
- Prompts that guide the scan
- Support-assisted setup for one-off flows
Session and Token Lifecycle Testing
Look for weaknesses in how sessions and tokens are handled:
- Login and logout flows
- Token refresh
- Timeouts
- Session invalidation
- 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.
Built for Global Apps
Test apps across store regions and languages, with dedicated test numbers and mailboxes for OTP delivery.
Built for Modern Auth Architectures
Handle SMS, TOTP, email and browser-based 2FA, client certificates, custom headers and scripted logins, on mobile and web apps, within one platform.
Clear Ownership Handoff
Findings are structured so mobile and backend teams can quickly identify responsibility boundaries and implement fixes efficiently.
