BankGo is a mobile banking app that lets customers check balances, move money, and pay bills. The team recently reworked the launcher and login flow to make sure tapping the app icon always returns the user straight to the sign-in screen. During a pre-release review, focus on how the login screen is registered and how it behaves inside the Android task stack when other apps are installed on the device.

GovToken is the governance token behind a popular DeFi lending protocol. To save users gas, the team built VoteDelegate — a contract that lets holders sign an off-chain EIP-712 'delegation permit' so a relayer can register their chosen delegate on-chain. The signature is verified with ecrecover and the recovered signer is trusted as the token holder. A guardian role exists to fast-track emergency delegations. Review the signature handling and the role setup.

FitLog is a fitness tracker that syncs your runs and workouts to the cloud. To make sign-in painless, the team integrated a third-party OAuth provider and handles the redirect back into the Android app through a custom URL scheme. Take a close look at how the app receives the authorization response and ties it back to the login request. Is the round trip actually safe from other apps on the device?

Review the authentication code for InsightLoop, an online survey and research platform used by Fortune 500 companies to gather confidential market research data. After a recent database breach, attackers were able to quickly compromise respondent accounts and access private survey responses containing unpublished business strategies and competitive intelligence. Investigate how user credentials are being stored and processed.

SecureGate is an enterprise VPN authentication service handling thousands of remote employee logins daily. The system was recently migrated from a legacy infrastructure and now uses a centralized Go-based authentication microservice. Security team is concerned about the cryptographic implementations used for credential storage. Review the authentication flow and database operations to identify weaknesses that could lead to credential compromise.

Review code for HealthTrack, a healthcare appointment scheduling application. The platform allows patients to book appointments and access medical records. Recently, the team implemented a password reset functionality to improve user experience. Examine the password reset mechanism to ensure it properly validates user identity.

Review code for a healthcare portal that allows patients to communicate with doctors and access medical test results. The system recently implemented a password reset mechanism. Some users have reported being able to reset other accounts' passwords. Examine the reset flow for security issues.

Your organization has developed an enterprise SSO portal that allows employees to sign in once and access multiple internal applications. The system uses SAML for authentication. Recently, the security team received an anonymous tip that there might be a critical flaw in the authentication system. Perform a code review to identify any potential vulnerabilities in the SAML implementation.

You're reviewing the code for an enterprise SSO provider that serves as an identity bridge for multiple applications. The system implements OAuth 2.0 flows to authenticate users across different services. The security team is concerned about potential weaknesses in the implementation after a client reported unusual authentication attempts. Focus your review on the OAuth authorization flow implementation.
