# Profile ## Profile Page The Profile page contains two sections: API keys and Project access. ![Profile page with an active key and access to projects](https://4002529329-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LwOmaDlbanAQ-7fhd89%2F-M-QFxhbBlUoXF6KvbPH%2F-M-QT4OWJg7J2X04Zbbb%2FScreenshot_2020-02-06%20https%20preprod%20gen3%20biodatacatalyst%20nhlbi%20nih%20gov.png?alt=media\&token=c1d82dd4-e35a-4a0c-9111-fb92564dbf6f) ### API key(s) To download large amounts of data, an API key will be required as a part of the [gen3-client](https://gen3.org/resources/user/gen3-client/). To create a key on your local machine, click **Create API key**, which will activate the following pop-up window: ![API key creation pop-up window](https://4002529329-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LwOmaDlbanAQ-7fhd89%2F-M-QFxhbBlUoXF6KvbPH%2F-M-QUWrsezm4uF8t3ua4%2FScreenshot_2020-02-06%20https%20preprod%20gen3%20biodatacatalyst%20nhlbi%20nih%20gov\(1\).png?alt=media\&token=660b6db3-1e8b-4a7e-9925-d3044c4c166e) Click **Download json** to save the credential file to your local machine. After completion, a new entry will appear in the API key(s) section of the Profile page. It will display the API key `key_id` and the expiration date (one month after the key creation). The user should delete the key after it has expired. If for any reason a user feels that their API key has been compromised, the key should be deleted before subsequently creating a new one. ### Project Access This section of the Profile page lists the projects and the methods of access for the data within in the *BDC-Gen3* system. If you do not see access to a specific study, check that you have been granted access within [dbGaP](https://www.ncbi.nlm.nih.gov/gap/). If access has been granted for over a week, contact the BDC Help Desk:
