  1. OMFG!!! Do *NOT* put passwords or any secrets in your claims… the JWT itself is *NOT* encrypted/secure, the payload is only base64 encoded, the signature only confirms authority.

    JSON.parse(atob(YOUR_TOKEN.split(‘.’)[1]))

    This is a *REALLY* bad example.

      1. The problem is, even putting it in the example is really bad form and should be updated… should include stuff like created, expires, and the user’s id. Having the password in the example could lead to false confidence and others following by this example.
