Amazon Cognito

What is Amazon Cognito? Amazon Cognito is a service used for authentication, authorization, and user management for web or mobile applications.

Amazon Cognito enables users to sign in through social identity providers such as Google, Facebook, and Amazon, and through enterprise identity providers such as Microsoft Active Directory via SAML.

Amazon Cognito authorizes a unique identifier for each user and acts as an OpenID token provider trusted by AWS Security Token Service (STS) to access temporary, limited-permission AWS credentials.

The two main components of Amazon Cognito are

User pools are user repositories (where user profile details are kept) that provide sign-up and sign-in options for your app users. User pools provides

● sign-up and sign-in services through a built-in customizable web UI.

● user directory and user profiles.

● security features such as multi-factor authentication (MFA), checks for compromised credentials, account takeover protection, and phone and email verification.

● helps in customized workflows and user migration through AWS Lambda triggers.

Identity pools provide temporary AWS credentials to the users so that they could access other AWS resources without re-entering their credentials. Identity pools support the following identity providers

● Amazon Cognito user pools.

● Third-party sign-in facility.

● OpenID Connect (OIDC) providers.

● SAML identity providers.

● Developer authenticated identities.

Amazon Cognito is capable enough to allow usage of user pools and identity pools separately or together.

Pricing Details: (pay only for what you use)
