You can get User Name & Password which you hae sent to user as query string. Read the query string & compare those values with data base values. If value's are matching then user is valid user & then you can enable this user.

So if you are having something like user confirmation page(This is the link you are going to send to user.. htt://localhost/UserConfirmation.aspx?UserName="Test"&Password="1234"),on Page_Load you can check the values,

string userName = Request.QueryString["UserName"];
string password = Request.QueryString["Password"];

// add logic to get data from database // -> You can send this username & password to database & check if there is any user present if yes its valid user.

i.e. select userName from UserTable where username = userName and password = password

If this query gives one result record then user is valid you can enable that user.

Please Note :- Its advised that when you send data in querystring try to encrypt it.
