Delete other users from Netflix?

How can I kick users out of my Netflix account without them noticing

Not at all. Just change your password.

How do other users get into your account? Or are you talking about different profiles here?

Well If you have thrown them out, then they will notice it simply because they can no longer access it…

Or you can just change the password.

Then the old one just doesn't work anymore… Perhaps then said people think that they entered the password incorrectly…
