Things you should put in your claims...
* token id
* real name
* account id
* email address
* user's roles/groups
example, here's a claims section from a devauth application I wrote.
{
jti: "GENERATED_UUID_FOR_THIS_TOKEN"
iss: "https://AUTHENTICATION_SERVER/"
aud: "https://APP_SERVER/",
iat: 1564526297, // Issued, seconds since unix epoch UTC
exp: 1564569497 // Expires, seconds from unix epoch UTC
sub: "USER_ID",
eml: "EMAIL_ADDRESS",
fnm: "FIRST",
lnm: "LAST",
aff: ["AFFILIATION",...]
rol: ["ADMIN",...]
}
