eKYC (Electronic Know Your Customer)

eKYC is the digital way of satisfying Know Your Customer rules, the regulatory requirement in banking, finance, and other regulated sectors to verify who a customer is before opening an account. Instead of a branch visit and a clerk checking documents, eKYC does it remotely: scanning a government ID, matching a live selfie against it, and cross-checking authoritative data and watchlists.

It sits at the intersection of regulation and onboarding experience. Done well, it turns a process that once took days into minutes and lets regulated businesses onboard customers entirely online. Done badly, it adds friction that loses applicants, or it lets fraud through. The strength of its document, biometric, and liveness checks is what separates the two outcomes.

In CIAM, eKYC is the regulated, higher-assurance end of identity proofing. It produces a verified identity at a known assurance level that can gate high-value actions, and it is increasingly delivered through standards such as OpenID Connect for Identity Assurance and, in emerging models, reusable verifiable credentials so a customer proofed once can present that assurance elsewhere.
