Single post in Two-Factor Authentication

I don't want to enable 2FA until I can disable it, so I want to ask a question since I can't just test it... are you saying you have to enter the 2FA code *every* time you log in, even if you're using the same device? I don't want the normal session timeout to be increased, but I would like it if the 2FA could be optionally remembered on a single device for 30 days. I know it's technically less secure but, well, it still prevents most remote attacks, and people who share devices can leave the remember box unchecked for increased security.
