How do I verify a token?

How to validate JWT token in Python?

JWT validation in Python

This validate method handles basic claims validation out of the box (the expires at and not before claims). To use JWTs effectively, you will want to use their standard claims, such as the issuer (do you trust who created this token?) and audience (is this token intended for you?).

How to verify a JWT token in Java?

First, we create a validator with the chosen algorithm and secret. Then we provide it the unsigned token data and the provided signature. Then the validator generates a fresh signature and compares it against the provided signature. If they are equal, we have verified the integrity of the header and payload.

Where can I find my token number?

You can call your company helpdesk and they can provide you with your token serial number.

What does JWT verify () do?

jwt.verify(token, secretOrPublicKey, [options, callback])
