Yoti is one of the most prominent names in age assurance for adult content, offering both document-based ID verification and camera-based age estimation (no document required). Its facial age estimation is certified by the Age Check Certification Scheme and explicitly supports UK Online Safety Act compliance workflows, making it a realistic drop-in for operators who need Ofcom-acceptable methods. The reusable Yoti digital ID app also reduces repeat friction for returning users.

As with any facial-biometric vendor, review their data-processing terms carefully if you serve EU users, where regulators scrutinise biometric handling closely.
