Log in screen when start remote access session

Hi,

i remember some time in the past that when i tried to remote access to a pc with admin password via team viewer, the windows log in screen always appeared first. I had to use the correct password of the admin account to successfully log in and then do my work. Now, there is no log in screen. The session starts by showing the desktop first. I must say that at both cases, the admin account was already loged in. So, previously we had double authentication, a teamviewer and a windows pass, and now we have only the teamviewer pass. Is it possible to go back to the double authentication? How can i change the settings to achieve this?

Thank you in advance
