User cookie no more available

I’ve upgraded to 6.2.5 version from 5.4.2
With the 5.4.2 I’ve been using the grafana cookies (grafana_user) that would allow me to run another application on the server and use this cookie to identify users.
I see that this has been removed now.
I’ve been searching how to add this to currently running version (6.2.5) but not able to find it.
Do you think that it is still possible?

no this cookie is no longer available

Is there any other way to identify users?

Great question! Is there any other way to identify users or team?
