Retrieve Password using Email Address in DNN 4.5+

You can set your portal to enable users to retrieve their password by supplying their email address. This is handy because people know their email addresses, whereas their user name may have been randomly chosen.

Problems with retrieve password using an email address will occur when you have a user account on one portal and then try to create a user account on another portal within the same DNN installation. When requiredUniqueEmail is set to true, each user account must have an email address which is unique across all portals in the DNN installation. This problem can be overcome by using the same user name and email address for multiple user accounts.

You can set your DNN to retrieve password using an email address by setting the

requiresUniqueEmail field in the web.config file to true ( requiresUniqueEmail="true" ). The web.config file is located in the root folder of your DNN installation.

To find out if your portal enables retrieve password using email address check the REquiresUniqueEmail option under User Accounts Settings.
