Hello, my name is Chris. To logon to Netflix, just enter Netflix.com in the address bar of your internet browser. Enter the daughter's email address and password, then select add profile. This will allow you to keep suggestions and your watch list tailored to your taste. Any issues, let me know.
If you're referring to watching on a smart TV, you will have to refer to your TV manual to see how to access the internet browser. Obviously you'll need a hard wired or wireless connection to your tv if that is the case.
