Many people see connection security warning when you try to connect to a remote computer using RDP services. Are you also looking for ways to disable Remote Desktop Connection security warning? This article will cover several ways to ignore Remote Desktop Connection security warning.

But let's be clear about one thing: warning messages/pop-ups seen by end-users over RDP connections are a good thing. If there is a potential risk of compromise, Microsoft wants you to be warned. Sure, sometimes it can be perceived as a nuisance, but please don't click on it without reading what it's trying to tell you in the first place!

How to disable Remote Desktop Connection security warning [3 solutions]

Are you also facing trouble with the Remote Desktop Connection security warning? Do you want to know how to ignore this warning? This post will provide you with three options.

Solution 1. Add a new registry key

How to ignore Remote Desktop Connection security warning is an old question. You can ignore certificate checking for all RDP Connections (use it at your own risk). This is a very simple solution.

Just add a new registry entry as shown below:

reg add "HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client" /v "AuthenticationLevelOverride" /t "REG_DWORD" /d 0 /f

Solution 2. Import the remote device's certificate

You have most likely decided to connect to the computer via RDP through the IP address. I'm not sure how many users believe this is the correct method. However, you will always receive a warning because you are trying to connect using an IP address instead of a name and the certificate cannot be used to validate the IP address. But what do we do if RDP with names still generates warning messages?

Step 1. Export the remote device’s certificate (no private key needed).

Step 2. Create a GPO that disperses the self-signed certificate from the remote device to the local device.

Step 3. Import the remote device’s certificate into a new GPO at “Computer Configuration” > “Policies” > “Windows Settings" > "Security Settings" > "Public Key Policies" > "Trusted Root Certification Authorities".

Step 4. This will install the device’s certificate accordingly on the local device. So the next time you RDP using the remote device’s name, the warning vanishes.
