Why do you still rent a house in the same city with photos of your ID card and real estate license? Is it safe?

Renting a house in the same city now requires real estate certification. In fact, this is to protect the rights and interests of renters, but also to protect the rights and interests of lessors. This can prevent second-hand landlords. As for your ID card, I didn't even look at it. Because I have registered as a member of 58 cities for two years, I need to log in when I need to release rental information. After the lease is completed, the lease information is deleted.
