- Typical scenarios where using JWT is a good idea
- Typical scenarios where using JWT is a bad idea!
- Principles of Zero trust architecture and why you should always validate
- Best practices to thoroughly validate JWTs and potential vulnerabilities if you don’t.
- Use cases when encryption may be required for JWT
