What is Identity provider (IDP)?

An IDP (Identity Provider) manages, stores, and helps to secure digital identities. IDP manages the list of users that have access to certain resources within a network or an enterprise and offers secure authentication and authorization once the user (who wishes to access resources) tries to sign in. An IDP can use multiple modes of authenticating users including social login, email login, or credentials (account already created on that particular application). IDPs are mostly used in cloud computing to manage and store user identities. By using an identity provider, users can use their social networking platforms to prove their identities instead of creating a new account on a platform.
