In this article, I will show you how to fix the “Your Credentials Did Not Work” error while using (RDP) Remote Desktop Connection feature in Windows 10/8/7.
In Windows 10, we can use the remote desktop feature to connect systems remotely. This blog talks about an issue in which one is related to credentials used in Remote Desktop connectivity.
Genuinely, while connecting systems remotely, recently I received the following error.
Your credentials did not work
The credential that was used to connect to did not work. Please enter the new credentials.
The logon attempt failed.
In this issue, I was sure that the credentials were correct. Even it worked fine with other computers but one of my machines start throwing this error.
