The module has not got this feature, and although it is easy to add we are not likely to include it.

The feature would open up a significant security risk, especially with brute force hacks. For this reason, we think it is best avoided.

Unless you can think of a good way to avoid that?

Yeah,

Have the CRM sync contacts with the DNN site, that then allows users to manage pass and access using the DNN system. AKA Normal access.

We have done this for Microsoft CRM.  http://www.interactivewebs.com/crm

We have similar functionality that we build into our modules. As an example, we have a license management tab: http://www.interactivewebs.com/Suppor...
that if you log in with an account that has the same email address as your license purchases, the module picks up on your history of module license purchases and activation, and will display your related data directly to you as a users.

We have the ability as administrators, to simulate via way or URL or email address, the details that a user would see when hitting that page. The idea is that we do not want to play "log in, log out" all the time, but we remain logged in as an admin, but stimulate the page and module to give us the same experience that a user would see.

Can I suggest that this approach may work for you. Rather than actually logging in and out all the time, just stay logged in as a user, and make the modules that display the data you see, have the ability to "simulate" a user, but way of user ID etc. 

Secure, and easier to use.

I was assuming that you have some sort of module that interacts with that already, and that your module developer could add functionality like I describe.
