Are there plans to introduce either of these features, and if so, is it known when?
Verified Push currently is not supported by Duo Authentication for Windows Logon. We would very much like to require digits to be entered.
Remembered Devices is supported but not for RDP connections. I would very much like to pair these two features so that the pushes are more secure but the tradeoff is users don’t have to do them as often.
I can see Remembered Devices being trickier since you can’t pass cookies back and forth to the RDP client, but the computer being connected to could itself save trusted username/IP address combinations and when they expire.
If these features aren’t already planned consider this a request for them.
