Digital Identity
The online representation of a person or entity, comprising digital attributes, credentials, and activity data used for authentication and authorization.
What is Digital Identity?
Digital identity is the comprehensive representation of an individual or entity in digital systems. It encompasses all information used to identify, authenticate, and authorize users across online services: personal attributes (name, email, phone), credentials (passwords, biometrics, certificates), identifiers (user IDs, social IDs), and behavioral data (login history, preferences, activity logs). Digital identities are managed by identity providers (IdPs) like LoginRadius, which store, protect, and provide these identities to applications via standards like SAML, OIDC, and OAuth. Strong digital identity management is foundational to CIAM, enabling secure authentication, personalized experiences, and regulatory compliance.
Analogy
Think of digital identity like a digital passport that proves who you are online. Just as a physical passport contains your photo, name, and nationality, your digital identity contains your email, profile data, login credentials, and activity history that proves you are who you claim to be in the digital world.
Types and Use Cases
Components of Digital Identity:
- Core Identity: Name, email, phone, date of birth, unique identifiers
- Authentication Factors: Passwords, biometrics, hardware tokens, OTP
- Profile Data: Preferences, address, profile picture
- Activity History: Login logs, consent records, transaction history
- Federated Identities: Linked social accounts, enterprise SSO identities
Common Use Cases:
- CIAM Platforms: Centralized digital identity storage for customer-facing apps
- SSO: Single digital identity used across multiple applications
- KYC/AML: Verified digital identity for financial services compliance
- Personalization: Using identity attributes to customize user experiences
- B2B Identity: Managing partner/employee digital identities with role-based access

}Digital Identity vs Physical Identity
Digital Identity
Physical Identity
Digital identity exists online and can be verified instantly,
physical identity requires in-person verification or physical documents
Digital identity can be portable across services (federation),
physical identity is typically tied to specific institutions (DMV, passport office)
Digital identity can include behavioral data and preferences,
physical identity is limited to static attributes
Best Practices for Digital Identity
- Minimize Data Collection: Only collect identity attributes necessary for the service (data minimization principle)
- Implement Strong Auth: Protect digital identities with MFA, risk-based authentication, and breached password detection
- Maintain Audit Trails: Keep comprehensive logs of identity changes, consent updates, and access events for compliance

FAQs
A user account is a specific record in an application (e.g., your Netflix account), while digital identity is the broader concept encompassing all your online identities across services. With CIAM and SSO, one digital identity (managed by an IdP like LoginRadius) can be used to access multiple applications. Think of digital identity as your 'digital self' online, and user accounts as the specific services you access with that identity.
Digital identity verification happens through: (1) Authentication - proving you own the identity via passwords, biometrics, or OTP; (2) Federated Login - trusting identities from known providers (Google, Facebook, SAML IdP); (3) Identity Verification - verifying real-world identity via documents, biometrics, or credit checks (KYC/AML). LoginRadius supports all three methods, allowing you to choose the appropriate verification level for your use case.
Under GDPR and other privacy regulations, users have the 'right to be forgotten.' When a user deletes their account, their digital identity should be anonymized or deleted (depending on legal retention requirements). This includes removing profile data, revoking active sessions, deleting consent records, and removing from marketing lists. LoginRadius provides APIs for account deletion and GDPR compliance, including cascading deletes across linked applications.
