Answer
The server verifies a JWT using its signature.
When a JWT is received, the server uses a secret key to verify the token's signature, ensuring it's not tampered with. This process confirms the token's integrity and authenticity without a database lookup. For example, a server might use an HMACSHA256 algorithm to verify if the JWT was issued by itself.
