What Is JWT and Why Should You Use JWT

Fifteen minutes that explain what a JWT actually contains, how the signature proves the payload has not been tampered with, and when a plain session cookie is the better design. The right first watch before implementing token auth, and a useful correction for the 'JWT everywhere' habit.
