Businesses use Customer Identity and Access Management (CIAM) software to manage customer identities and provide a secure, seamless login experience for their websites, applications, and online services. CIAM solutions enable businesses to handle customer identity data, preferences, and profiles at scale. These tools allow customers to self-register, log in, authenticate, and manage their profiles, including consent and other preferences. CIAM software helps companies create smooth, user-friendly online experiences. Many solutions offer multi-factor authentication (MFA) for enhanced security, as well as federated identity features like single sign-on (SSO) or social login, so customers can authenticate once and gain access to multiple company applications. These solutions also help businesses manage customer consent and preferences to ensure compliance with data privacy regulations like GDPR and CCPA. While similar to Identity and Access Management (IAM) software, CIAM is distinct in its focus. IAM is used for managing internal identities, such as employees or contractors, whereas CIAM is designed for customer identity management. In IAM systems, user provisioning is typically handled by IT staff, but CIAM allows customers to self-register and update their own profiles, offering more flexibility and control for end users.
