Supply username and password to mstsc

  • 772

In previous versions of the remote desktop client there were methods of passing in the password through various methods. Has anybody found a good method using the latest remote desktop client? I'm aware of LaunchRDP but that doesn't meet our needs.

Perhaps somebody knows the algorithm so I can dynamically assemble RDP connection files?

  1. I still have connection files with saved passwords that were saved and they still work.

    The .rdp format is actually fairly decently documented, see these:

    Some documentation about the password hashses is at:

    1. Open Powershell
    2. type ("YourPassword" | ConvertTo-SecureString -AsPlainText -Force) | ConvertFrom-SecureString;
    3. Add the resulting hash to the rdp file as password 51:b:<hash>

    Note: This hashes the password per user, so sharing the rdp file with someone else means it wont work.
