Okta for Developers is a platform providing customizable, secure identity and access management (IAM) services to protect applications, APIs, and infrastructure, allowing developers to add authentication and authorization features without building them from scratch. Developers can use Okta's APIs and SDKs to integrate features like single sign-on (SSO), multi-factor authentication (MFA), and passwordless login, enabling them to manage user identities, define access policies, and customize sign-in experiences.
