Platforms Use Biometrics to Block Bots

Major social platforms are actively testing identity checks that require a biometric or device passkey (Face ID/Touch ID), decentralized third‑party proofs, or full ID verification to prove an account is human. Those choices range from lightweight on‑device checks to heavy-handed ID checks and carry different privacy and adoption tradeoffs. — The move reframes platform trust: solving automation and misinformation by verifying bodies/IDs shifts the battleground from algorithms and content to identity infrastructure, with lasting implications for anonymity, surveillance, and civic participation online.
