If you want to run Jupyter in a context where the token authentication should be disabled, use the
--LabApp.token=''
command line flag. This will users allow to access the Jupyter without entering any credentials.
Note that this has security implications and everyone that can access the Jupyter server IP & port will be able to access Jupyter! I recommend to at least add another layer of authentication like HTTP basic authentication if you use Jupyter in a public network.
