jti – JWT ID, a singular identifier for that token, handy for preventing replay attacks or blacklisting
Perfect for cellular applications – JWTs are lightweight and stateless, they’re perfect for cell authentication. They perform smoothly with APIs and assist lower unnecessary server load, which might appreciably Increase overall performance in mobile environments.
