Best practices
- Always use HTTPS to prevent token interception
- Keep secrets out of client‑side code
- Set short expiration times (15–60 minutes)
- Implement refresh tokens for longer sessions
- Validate all claims (issuer, audience, expiration)
Common pitfalls
- ❌ Storing JWTs in localStorage (XSS risk)
- ❌ Not rotating secrets
- ❌ Using weak HMAC keys
- ❌ Ignoring expiration validation
Code Examples
Decode and inspect any JWT
var handler = new JwtSecurityTokenHandler();
var jsonToken = handler.ReadJwtToken(yourToken);
var header = jsonToken.Header;
var payload = jsonToken.Payload;
var isExpired = jsonToken.ValidTo < DateTime.UtcNow;
