-A user pool is a directory of users . It integrates with other SSO providers such as Google, Amazon and Apple. This allows customers to create a user account in the user pool by simply authenticating with their chosen SSO provider. It uses OpenID Connect or SAML to delegate authentication to third party identity providers. Additionally, it can be used to store custom attributes about users. Users can be assigned read/ write permissions to these attributes when the user pool is configured.
