How to prevent a remote password from being stolen?

Question

Passwords

Hello. The task is this: you need to connect to many users via TeamViewer, for example, or AnyDesk to perform a certain kind of task. These tasks require you to sign in to my account on one site. It became interesting how to make it so that users would not be able to steal at least the password from my account using all sorts of keyloggers and other spyware? 2FA is not and is not provided in this case...

Answer 1

With such a connection scheme - no way. Well, except that after each connection you will install the anti-virus / anti-spyware scanner with your own hands and carry out a full system scan, only after that you will start working. And even this will not give a 100% guarantee.
If you want guarantees - change the scheme of work.
A simple option: after each such connection, urgently change the password.

Answer 2

Either 2FA or change the password every time.
Or something perverted, for example, if the site is simple, then log in to yourself, and transfer a cookie to the remote machine, and do not forget to close the session.
