I've been asked just once by a provider to give a copy of my driver's license. In fairness to her, she was a newbie to the profession; so I refused gently and explained why I thought that was a bad idea. We made other arrangements.
She must have been ok with how I handled it, as I booked her for only 2 hours, and at the end of that period she asked if she could spend the night,
gratis. In many respects, that was the best session I've ever had.
Only had a provider ask for a face pic once, but she sent hers first, and she'd committed to the date before she made that request. Worked out just fine; she's one of my favorites, and I'm looking forward to seeing her sometime soon.
Cheers,
