[keycloak-dev] User Device Activity

[Federico Michele Facca]

Hi Pedro,

Nice feature but why considering request from same ip as from the same device?
If you are using a fixed connection with several devices using it, then it may be easily  the case that different devices have been used.

Cheers,
Federico
