Pay only for what you use. No minimums.
If you are using Amazon Cognito Identity to create a User Pool, you pay based on your monthly active users (MAUs) only. A user is counted as a MAU if, within a calendar month, there is an identity operation related to that user, such as sign-up, sign-in, token refresh, or password change. You are not charged for subsequent sessions or for inactive users within that calendar month.
| Pricing Tier (MAUs) | Price per MAU |
| First 50,000 | Free |
| Next 50,000 | $0.00550 |
| Next 900,000 | $0.00460 |
| Next 9,000,000 | $0.00325 |
| Greater than 10,000,000 | $0.00250 |
For users who sign in through SAML or OIDC federation, the price for MAUs above the 50 MAU free tier is $0.015 per MAU. Using the Federated Identities feature to get AWS credentials for authenticated or guest users is always free with Amazon Cognito. Read more about our pricing here.
