Customer Identity and Access Management (CIAM) platforms help businesses securely manage the identities of their customers, users, and external audiences. They provide the systems needed for customer registration, login, authentication, profile management, consent handling, and access control across websites, mobile applications, and digital services.

As organizations deliver more digital experiences, customers expect convenient access without compromising privacy or security. CIAM solutions help businesses meet these expectations by combining user-friendly authentication with strong identity protection.

What Is CIAM?

CIAM is a category of identity management technology designed specifically for customers rather than employees. Unlike workforce identity systems, which focus on internal users and company resources, CIAM platforms are built to support large numbers of external users.

They help businesses manage customer accounts throughout the identity lifecycle, from registration and authentication to profile updates and account deletion.

How CIAM Works

CIAM platforms provide a centralized layer for customer identity and access management.

1. Customer registration: Users create accounts through websites, mobile applications, or other digital channels.
2. Identity verification: The platform can verify email addresses, phone numbers, or other identity attributes.
3. Authentication: Customers sign in using passwords, passkeys, social login, or multi-factor authentication.
4. Access management: The system determines which applications, services, or information a customer can access.
5. Profile management: Customers can update their personal information, preferences, and account settings.
6. Monitoring and protection: Suspicious login attempts and unusual account activity can be detected and addressed.

Popular CIAM Tools and Platforms

Several platforms provide customer identity capabilities for businesses of different sizes.

• Auth0: Offers developer-focused customer authentication, social login, and access management capabilities.
