I am using the Duo integration with RDM and it's awesome.
Duo has a feature that will allow users to save their devices for X days/hours to avoid re-authenticating.
They also have a feature to trust networks.
I tried both of these and I am not seeing any changes in the RDM login process.. when it does the Duo authentication.
I'm guessing these features need to be integrated into RDM?
Indeed it's not integrated. I will check with the devs if it's easy to add.
I'm actually working on the trust networks feature and I'll have a look at there trusted devices feature.
It's plan to be part of the RDM 12 released.
