How should secrets and tokens be stored securely on mobile devices?
Answer
Avoid storing secrets in plain text.
Use secure storage:
- iOS: Keychain (+ Secure Enclave when relevant)
- Android: Keystore + encrypted preferences
Also:
- Prefer short-lived tokens
- Rotate refresh tokens
- Protect against screenshots/logging leaks
Security is layered: storage, transport (TLS), and server-side validation all matter.
