Sign on to ATV4 with the iOS client on a phone or tablet to prevent children from gleaning the PIN

Is it possible to allow a user to sign-in on ATV 4 Plex using the iOS Plex client on an iPhone, or other mobile device.
Reason for the request is that if other people are in the room or near by, say children, they could see the password of someone trying to login. My niece and nephew have figured this out in regards to their parents account.

I’m sorry if this is a repeat, I tried to skim through all the posts in this category but could not find it there.

I appreciate all the hard work done by the Plex Team. I’ve been happily using it for many years.

Regards,
Tyler.
