# Design Studio Data Flow
The **Design Studio** user interface captures data provided by the user to build onboarding journeys, including their flow and UI elements. This data also includes authentication-related information such as username, email, and password. The underlying services used to store this data are as follows:
* Username, email and password are stored and managed in [AWS Cognito](https://aws.amazon.com/pm/cognito).
* UI element configuration data (excluding any sensitive data) is stored in [GitHub](https://github.com/).
* API keys and credentials of external providers are securely stored in [AWS Secret Manager.](https://aws.amazon.com/secrets-manager/)
* Flow-related components are stored in [AWS DynamoDB](https://aws.amazon.com/pm/dynamodb/).
# Digital Onboarding Data Flow
The **onboarding frontend** typically captures end-user data, including PII (e.g., first and last names, birthdate, and mobile number) and user identity documents.
The **backend** orchestrates the steps defined in the corresponding journey, aggregates, and transforms the data before sending it to external providers.
Journey data is stored temporarily to facilitate execution from start to finish. By default, this duration is set to 2 hours, which can be configured at the application level.
