What is my username?

Thanks for the reply. However I am still locked out. I didn't see anything about resetting to the built-in administrator's username/password in he article you linked to. I did open the PRTG Administration Tool referenced in the article. On Administrator tab it shows Login Credentials for the Administrator Account. It shows the same email address and password that I entered online, but they still don't work. So I don't understand why I'm having this problem. I trided changing the password (to the same one) but it still didn't work.

Hi Rick,

Referring to the above mentioned article, kindly note that login credentials for PRTG consist of a Login name and Password.

The PRTG Administration Tool on the PRTG Core Server can be used to re-define the default Admin Login name and Password at any time (even without knowing the current credentials).

The Email Address, which is also shown in the "PRTG Administration Tool > Administrator"-tab indicates the recipient address for Alarms, Notifications or can also be used to redefined your password via e-mail. However, depending on your e-mail delivery settings the mail delivery may not be optional thus changing the username/password directly (instead of an per e-mail reset) makes more sense in this case.

Please configure a Login name and Password and use these two values to login into PRTG after saving the changes with the Administration Tool.

After you've re-gained access to PRTG with the default Admin, head to Setup > User Accounts and re-define the password of any other accounts.

Best regards,
Sebastian

Thanks!
