I noticed something strange, or it might be intended :P.
When I log in to the backoffice using Umbraco login, I can work continuously without any issues.
If I wait 20 minutes with inactivity, then I get logged out (expected behavior).
However, if I log into Umbraco again and continue the session, I am logged out every 5 minutes.
I can see in the logs that the token expiration is set to 299 seconds.
Do I need to set something to change this?
