Ach... I completely misunderstood... it looked to me like he was asking how to get into DotNetNuke using a querystring/post.  Nope... I do have something like that that i'm working on, however, which allows posting to another site to login (we'll call it "Credential Vault" for now).  Basically allows an admin to define one or more sites that can be logged in to and then the user would define their own credentials (username, password, token, whatever).  On the click of a button, would be logged into that external site. 

However, this isn't my "next in line" for release... I have another module that has higher priority to me personally.  Can't really give an ETA on this one, except "not too far out".

some years have passed by this post, but the problem is still here!

no one has found or developed a solution to this problem? I found this solution (http://dotnetnuke.montreat.edu/Single...) but it don't work for DNN5

Thanks!
