Allow successful MFA to be remembered for 30 days. It's clumsy having to use MFA every time the portal times out.

Yes, please! Gmail itself works this way and many other apps or sites (Evernote, in example) using Google Authenticator as MFA.
Otherwise we still to enter a code many times every single day.
As a temporary workaround I'm using Winauth on my PC, at least I can use copy & paste.
