Mouse Without Borders KeysNotMatched Error

Area(s) with issue?
Mouse Without Borders
Steps to reproduce
I have two machines that were connected. They have stopped working. Upon investigation I have found that they have spontaneously started failing to match the keys. Naturally, I have tried resetting everything and the error has persisted. Win 11 pro on one machine. Win 10 Home on the other. Again this hasn't been an issue in the past.

I've experienced the same issue, working setup, update and it broke. Various attempts in the user interface but only some of the computers would connect, and others failed. I found a workaround, when I manually changed encryption key to the same value on each computer in the settings file in:
%localappdata%/Microsoft/PowerToys/MouseWithoutBorders/
it all worked again. That suggests it's something in the user interface or one of the checks that's at fault.

I was having the same issue, but manually inputting the key did not fix the problem for me. The only thing that solved my issue was to delete the entire %localappdata%/Microsoft/PowerToys/MouseWithoutBorders/ folder in both computers.

Ran into this issue recently, I couldn't figure out why Mouse Without Borders wouldn't work for me anymore as the ui would only flash the border color.
I was on PowerToys 0.77.0, tried uninstalling, reinstalling, both from the Windows executable from github and from the Microsoft Store, upgraded to PowerToys 0.78.0, no luck.
It wasn't until yesterday when I switched to using the original Mouse Without Borders UI that I was able to get the feedback about the Keys Not Matching, which thankfully allowed me to find this issue, after deleting the folder in localappdata I was able to get Mouse Without Borders to work again.

I noticed that the value for properties > SecurityKey > value in settings.json on one machine wasn't being properly updated. It still had an old key saved, not the latest one I had typed into the Connect fields. I had tried entering the security key using the old UI but it hadn't persisted to settings.json, either.
I managed to manually replace this in the file, Refresh Connections, and now I finally have control of my second machine. That only took about 3 hours to fix, and only 20 minutes after I found this post!
There's definitely a bug here, both in the new and old UI. A new security key isn't being written to settings.json, regardless of which UI is being used.
in version 0.80.1.0 editing the json file directly is what fixed it for me!
Thank you for summarizing what I said. Manually replacing the security key in settings.json fixes the issue.
I had the same issue as well, it was connecting well before and one day it stopped connecting.
Tried changing to old UI and it shows key did not match. Then i tried the above methods and the following one works:
The only thing that solved my issue was to delete the entire %localappdata%/Microsoft/PowerToys/MouseWithoutBorders/ folder in both computers.
I was having the same issue. I had to manually edit the settings.json file and put the same key in there on my second machine. Once I did that it connected right away.
