@Gail-And-Bruno0 other hosts have mentioned saying something along the lines of:
"Hello! For everyone's security, we always must verify that the person we are handing keys to is the same person who made the reservation. (This is for your safety also!)
Please provide a clear photo on your profile so that we can recognize you when you arrive, and please be sure to have your ID with you!
Unless we are able to verify identities upon check-in, we cannot provide access to the listing.
(I am sure you would not want us giving the room you paid for to someone who wasn't you.)
Thank you!"
