Does OKX require face verification?

Could you please clarify the security measures employed by OKX, specifically whether they require face verification as part of their user verification process? As a user, I'm interested in understanding the level of security offered by the platform to protect my funds and personal information. Is face verification mandatory for all users, or is it a selective process based on certain criteria? Furthermore, what other security features does OKX offer to ensure a SAFE and secure trading environment for its users?
