How to turn off Facial recognition login

Hiya it turned itself on and I can't seem to turn it off. If I would like my sister to withdraw my cash I can't do it if I'm not bodily present together with her. What if I die or I would like my mom to use my account. I need to just give them. The passwords and e-mail. Password and that's it. In order that they login. At this state of one thing happens to me it's unattainable to communicate to my sister who isn't tech savvy how you can get my cash out.
