How to fix "Your credentials did not work" error in Windows?

Issue: Hello. I tried to establish a connection from my desktop to my laptop with Microsoft's RDP. When I try to connect, I receive the “Your credentials did not work” error. How do I fix this?

Solved Answer

When users are unable to connect to a remote system using Remote Desktop Connection, the “Your credentials did not work” error occurs. This error is particularly aggravating because it frequently appears even when users enter the correct credentials. The issue is usually not with the credentials themselves, but with Windows policies that block incoming Remote Desktop Protocol (RDP) connections or with issues with the system's username.

This error can have a number of consequences for users. For starters, it makes it difficult to remotely access and control another system, which is frequently required for tasks like remote troubleshooting or accessing files and applications on a different device. It has the potential to disrupt workflow and productivity, particularly for individuals who rely heavily on remote connections for work purposes. Furthermore, the error can cause confusion and frustration because users may believe they have entered the correct credentials, wasting time and effort troubleshooting the incorrect area.

Users can investigate various solutions to the problem. This may entail reviewing Windows policies related to RDP connections and ensuring that incoming connections are permitted. Verifying the system's username and ensuring that it corresponds to the username used for Remote Desktop Connection can also assist in resolving the error. Checking network settings, restarting the remote system, or troubleshooting network connectivity issues are some other possible solutions.

Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speeds. The best solution for your ultimate privacy is Private Internet Access – be anonymous and secure online.
