I am using 6.4 RC 14 and connecting to my unraid via https.

 

I noticed something recently and wondered if it was normal.  When I log into unraid, everything works as expected.  When I reboot my PC (not Unraid) and try to go to the unraid page, it pops up with the login prompt asking for username/password as expected.  But at that login prompt, if I hit Escape, then refresh the page, it goes right into the Unraid UI, no username/password required.  

Try logging in on another browser.  And give the name of the browser that you are using.  

I use Chrome.  trying to open it in Internet Explorer still requires username/password entry.  So its like the browser is remembering the session info
