Just in case you need to extract those passwords from mRemoteNG. Just use the External tools as per the below.
- Open mRemote and go to “Tools” > “External Tools”
- Right-click in the white space and choose “New External Tool”
- In the External Tools Properties, fill in a “Display Name”, “Filename” and some “arguments”.
In this scenario I filled in
"/k echo %password%".
- Go to the connection where you would like to reveal the connection and right-click on it and choose “External tools” > “Password lookup.
