Use HTTPS certificate pinning to lock Android apps to trusted servers. Tie your app to a specific certificate or public key hash, then verify every connection against this pin. If the server’s certificate or key doesn’t match, cut the connection,…
Use parameterized queries and validate every input. Restrict which columns and data are accessible through projection maps and strict mode. Encrypt sensitive fields and keep your content providers unexported unless you have an airtight reason. Key Takeaways Best Practices for…
Use the Android permissions model to protect both your users and your codebase. Always declare needed permissions in your manifest, check and request them at runtime with clear explanations, and never assume previous consent holds. Handle every user response respectfully…
Use explicit intents whenever you can to keep your app’s data away from prying eyes. Limit intent filters in your AndroidManifest and never use wildcards unless it’s absolutely necessary. Only request essential permissions, and always validate where intents come from…
Use internal storage for anything sensitive. Encrypt files before writing to external or shared locations, even if they seem harmless. We always rely on Android’s Keystore for managing keys, and newer scoped storage rules keep nosy apps out of your…
Use internal encrypted storage, enforce HTTPS for network calls, and never hardcode secrets. Regular audits and good cryptography habits help us safeguard user data. Combining strong authentication with minimal permissions gives our users privacy and peace of mind. Key Takeaways…
Secure mobile coding on Android begins with the smallest details, because that’s where the biggest risks hide. Something as simple as missing quotes in a script can cause failures that ripple across entire systems. Hardcoded secrets, unvalidated inputs, or sloppy…
Use Apple’s built-in hardware security like Secure Enclave, encrypt sensitive data with proper protection classes, and always use the Keychain for secrets. We clear secrets from memory as soon as possible with memory zeroing, and never store passwords or tokens…
Use HTTPS for all iOS API requests to prevent eavesdropping and man-in-the-middle attacks. Store authentication tokens in the iOS Keychain, not in plain text or code. Short-lived tokens with PKCE-enhanced OAuth 2.0 and multi-factor authentication (MFA) dramatically tighten mobile app…
A friend of mine once built a simple iOS login screen, thinking little of what could go wrong. Two weeks later, a test user tried pasting a long string of script tags into the username field. The app crashed. That…
