I don't know of an easy way to decypher the credentials, but you can reset the password to store in Plain Text.

1. Using a database manager like SQL Express Management, open the database table "dbo.aspnet_Membership"
2. Find your User account (if you can't find it, you'll have to first look up the account in the User table to get the UserID, then return to this table)
3. Change the Password Format to 1.
4. Change the User's Password.

The password for the account from now forward will display the password in Plain Text. Note that anyone who can open the database will also have instant access to the password as well, which is why normally credentials should be stored as hashed values

The alternative you might consider is if you can write the outside application to use and present the hashed credentials instead of passing the data around as Plain Text. That is what we did building an application that shares the DNN authentication provider..

Ok does anyone have an example of a vb.net (.aspx) app that can verify the username and password using the Microsoft Membership Component and MachineKey against a DNN database?

Thanks...
