Security is non-negotiable
Mobile apps handle sensitive data—user credentials, payments and personal information. Treat security as a product requirement, not an afterthought.
Authentication & authorization
Use proven identity providers (OAuth2/OpenID Connect) and avoid roll-your-own auth. Implement least-privilege access and short-lived tokens with refresh flows.
Data protection
- Encrypt sensitive data at rest using platform-provided secure storage.
- Use TLS everywhere and pin certificates when high assurance is needed.
- Minimize sensitive data collection and purge when no longer needed.
App integrity & supply chain
Use code signing, enable app attestation where possible and monitor third-party dependencies for vulnerabilities.
Secure updates
Deliver OTA updates safely: validate update packages, sign payloads and provide rollback mechanisms.
Conclusion
Design security into your architecture and validate it with periodic threat modeling and pentesting—especially before large releases.
