Amazon Cognito introduces tiered pricing for machine-to-machine (M2M) usage

Amazon Cognito introduces pricing for machine-to-machine (M2M) authentication to better support continued growth and expand capabilities. There is no change to Amazon Cognito's user based pricing (monthly active users or MAUs). Customer accounts currently using Amazon Cognito for M2M use cases will be exempt from pricing for 12 months. M2M pricing is based on the number of application clients configured for M2M authentication and the number of tokens requested for them. You can find details on our [pricing page](https://aws.amazon.com/cognito/pricing/). Amazon Cognito makes it easier to add authentication, authorization, and identity management to your web and mobile apps. In addition to supporting human identities, Cognito's M2M authentication enables developers to leverage machine identities to secure interactions between their services or across organizations. Developers can define machine identities and generate OAuth 2.0 tokens to authenticate them using Cognito user pools that are configured with the OAuth 2.0 client credentials grant. This pricing change applies to only to user pools configured in this way and is not applicable to any other OAuth 2.0 flows. Amazon Cognito is available in 29 AWS Regions globally.
