Facebook is the most secure social networking site among the major players, thanks to improved privacy controls and support for more secure two-factor authentication technology, but the social media sector as a whole remains vulnerable to different types of account takeover.

According to a study released Tuesday by access management vendor Cerby, the biggest area of concern common to the five platforms it studied — Twitter, Facebook, Instagram, TikTok and YouTube — was poor support for enterprise-grade authentication and authorization technology. Cerby said that support for cross-environment authorization technology like Simple Cloud Identity Management (SCIM) and Security Assertion Markup Language (SAML) would go a long way toward securing social media networks more effectively.
