User account getting locked while trying to connect to a remote machine

While trying to connect to a remote machine from workspace, MS Remote Desktop seems to be trying with the password more than one once, good enough to lock my ADS account.

I haven't saved my credentials with the app so just wondering if something is happening with the background. Is there a way to avoid this issue?

I'm on Mac and my version of Remote Desktop app is: 10.9.8 (2217)
