Does Facebook use secure browsing (HTTPS)?
Yes. Secure browsing (HTTPS) is a security feature that automatically encrypts your connection to Facebook. This helps protect your account by making it harder for anyone to access your Facebook information without your permission.
A secure connection is required to connect to Facebook and can't be turned off.
What should I do if someone is asking me to share a nude or sexual picture of myself on Facebook, or is threatening to share a photo that I already sent?
