A JWT (token) with the following properties will be generated:
```
{ "jti": "<<nonce>>"
, "iat": <<issued at unix timestamp in seconds>>
, "amr": "pwd@oauth3.org"
, "laa": <<last authentication at unix timestamp in seconds>>

The token will be passed back to the application in the following form:
```
