Account Sharing Prevention

Account sharing undermines revenue, security, and regulatory standing across every industry that extends services, access, or benefits to a verified individual. The business impact varies by context, but the underlying failure is consistent: credentials authenticate a device or a password, not a person.

The sharing patterns organizations encounter include:

• Subscription sharing: streaming, gaming, and SaaS platform credentials shared across households or networks, reducing paid subscriber counts and undermining per-seat licensing models
• Credential reselling: account credentials sold or rented to third parties, often at scale, as an informal secondary market
• Workplace license abuse: enterprise software licenses shared across more users than contracted, inflating effective usage beyond purchased entitlements
• Healthcare proxy access: patient portal credentials shared with family members or caregivers, creating privacy, consent, and regulatory exposure under HIPAA and equivalent frameworks
• Financial account access: banking and investment account credentials shared with family members or advisors, bypassing the identity assurance controls the account was opened under
• Gaming and competition integrity: account credentials shared to allow higher-skilled players to perform on behalf of the account holder, distorting rankings and competitive outcomes
• Credential exposure: every additional person using shared credentials is an additional vector for phishing, credential theft, and social engineering, expanding the account’s attack surface beyond the verified account holder’s control
• Gig economy credential sharing: unknown and potentially unqualified workers substituting for known, credentialed workers, creating potential liability

In regulated industries, shared account access creates liability that extends beyond revenue loss. A transaction or interaction conducted by someone other than the verified account holder may not meet the identity assurance requirements of the applicable regulatory framework, regardless of whether the account holder consented to sharing.

Daon provides organizations with the tools to control account sharing by binding account access to a verified identity established at enrollment through a government-issued document matched to a live selfie.

Server-side face biometric authentication confirms the same person at every subsequent interaction, tying access to the individual rather than device or credential possession. Presentation Attack Detection tested by iBeta to ISO 30107-3 Level 2 and injection attack detection aligned with CEN/TS 18099 apply at both enrollment and authentication, ensuring the face captured is always live and present.

For activities with inherent risk, continuous authentication uses risk signals and business-defined workflows to trigger reauthentication, confirming the same person who logged in remains present.

Daon secures over 2 billion identities across six continents, supporting account holders across 200+ countries. For global organizations, that coverage means the same enrollment and authentication controls apply regardless of where the account holder is located.
