PMM Login Timeout

Oh, and also using Chrome 65.0.3325.181 (32-bit).

I’ve been tracking how long the sessions have been running.
30 minutes
80 minutes
20 minutes
43 minutes
4 minutes

Each time it logs out the session, if I try to log back in, it fails to accept the saved credentials.
I close the browser and go to [url]http://ip-address-of-server/graph[/url].

Because the duration of each session is different, I’m beginning to think that this may not be a setting.
