On first installation of DotNetNuke® DNN your website will have two default users configured with two default passwords. These users are Host and Admin. The first thing you need to do is change these passwords.
1. Go to your new Website
- Open Internet Explorer and type in the web address, i.e. url, of your site for example www.ictkey.com.
The default SuperUser Account is Host and the password is Host
If your Website Hosting Provider installed DotNetNuke® DNN for you then they may have configured a different User Name and Password for example if you use www.PowerDNN.com they configure the SuperUser Account Name as host password hostdnn .
It is very easy to find out the default user names and passwords as they are displayed on the front page of your website, see screen shot below. This is why the first thing you need to do is change the passwords.

2. Login to your new Website
Click on the Login link, by default the link is positioned under the search bar to the right side of the page.

Type in the User Name and Password using the default User Name host and password host or exactly what is displayed on your websites front page. Click the Login button.

3. Change the Host Password
Click the Host link in the Menu bar, then click Host Accounts

The User Accounts Page is displayed, at this point if your account is called host, click on the H link alternatively click on the All link to display all accounts.
Click the Pencil icon to the left of the Host account name

Click the Manage Password link

Enter the password you've just logged in with into the Current Password field
Enter your new password into the New Password Field
N.B. I recommend you use a Strong Password i.e. over eight characters using Upper and Lower Case characters, numbers and symbols. I recommend that you test your password strength at Microsofts Password Checker page.
Enter your new password again to confirm it into the Confirm Password Field
Click the Change Password link

That's it, you have now successfully changed your SuperUser Host account password.
