Verisoul Account Linking is an identity verification tool that automatically detects when multiple accounts are operated by the same person. The system analyzes various account attributes including device fingerprints, email addresses, phone numbers, IP addresses, and behavioral patterns to establish connections between accounts. The platform generates a real-time account graph that visualizes relationships between accounts with match confidence scores. This enables organizations to identify repeat sign-ups, account sharing, spam operations, and coordinated fake account networks. Account Linking works as part of the broader Verisoul platform which includes complementary fraud detection capabilities such as bot detection, device fingerprinting, proxy/VPN detection, email intelligence, and geolocation analysis. The system can detect various fraud patterns including account takeover attempts, payment fraud, and geo-blocking evasion. The tool provides API access for integration into existing authentication and account creation workflows. Organizations can use the account linking data to enforce policies around duplicate accounts, prevent abuse of promotional offers, and identify coordinated malicious activity across multiple user profiles. Verisoul offers a dashboard interface for investigating linked accounts and reviewing match confidence levels between different user profiles.
