1. End-to-end encryptions. 2. Use the https protocol. 3. SSL pinning so your app only talks to trusted servers to prevent "man in the middle" attacks. 4. Token-based authentication that expires after a while. 5. Do not store keys on your code; use runtime environments or, better yet, an online storage like Amazon key management service, etc

When handling sensitive data in mobile apps, communication between device and server should be encrypted. Data sending to the server and response coming from the server should be encrypted and decryption should be done at both ends. Apis should only work with authorized users and a proper token refreshing mechanism should be implemented. SSL pinning is also an important part for securing communication.

To ensure secure API connections in mobile apps, can follow industry-standard practices and enforce robust measures underneath: 1. Encrypted Communication: All API traffic is secured using HTTPS with TLS 1.2 or higher. 2. Certificate Pinning: Prevents man-in-the-middle attacks by validating server certificates against known ones. 3. Token-Based Authentication: Use secure tokens like OAuth 2.0 with short lifespans and refresh mechanisms. 4. Secure Data Storage: Encrypt sensitive data at rest using device-provided secure storage. 6. Regular Security Audits: Conduct vulnerability scans and penetration testing periodically. These practices ensure data integrity, confidentiality, and compliance with security standards.

We ensure secure API connections in our mobile app through: -HTTPS with TLS 1.2/1.3 for encrypted communication. - OAuth 2.0 and token-based authentication (e.g., JWT). - Certificate pinning to prevent MITM attacks. - Secure storage of API keys (e.g., Keychain/Keystore). - Rate limiting and input validation for API hardening. - Regular security audits and adherence to OWASP best practices. A layered approach ensures sensitive data stays protected.

1. Enforce HTTPS for all API communications. 2. Use SSL certificate pinning 3. Use an appropriate BFF layer and never expose any sensitive credentials to the app side 4. Use hardware backed key-stores to securely store tokens 5. Use access control mechanisms 6. Use additional strong security mechanisms on non-secure communications (Ex. header enrichment cases) to prevent misuse as much as possible 7. Regularly conduct security audits

To enhance API security for mobile apps, start by using HTTPS to encrypt data in transit and token-based authentication like OAuth or JWT for secure access. Implement rate limiting and role-based access control (RBAC) to prevent abuse and unauthorized access. Encrypt sensitive data at rest and use certificate pinning to defend against MITM attacks. Secure API keys using environment variables and obfuscate app code to protect secrets. Regularly update and patch APIs, perform penetration testing, and monitor API activity for anomalies. Enforce HTTPS with HSTS, validate inputs, and use an API gateway for security policies. Finally, ensure compliance with relevant standards like GDPR or PCI DSS.

Store API keys and secrets securely (e.g., using **flutter_secure_storage** or platform-specific secure storage). Avoid hardcoding sensitive information in the app. Use environment variables or server-side configurations for sensitive keys. Use SSL pinning to ensure secure server communication. Obfuscate the app code using Dart obfuscation. Implement reCAPTCHA or similar mechanisms for bot protection. Use backend services to handle sensitive operations instead of client-side logic.

Various examples that have come across during my career were using TLS encryption OAuth token. Expiring those tokens in periods of time and obvious obfuscate code. Helps alot

1. Always use HTTPS Protocol for safe communication. 2. Implement SSL for secure connection. 3. Use a token-based system to verify user identity. 4. Create tokens based on the users role or permissions. 5. Don't store any secret information directly in app. 6. Use Encryption algorithms for store data locally. 7. Always send data in a safe, encrypted format when calling APIs.
