Sign up for the CGC


There are two ways to sign up for the CGC:

  • Register via an external account - If you already have an account with eRA Commons or NIH CIT, you can register on the CGC using the associated credentials. The easiest way to access dbGaP-regulated Controlled Data on the CGC is to register using your eRA Commons account.
  • Register via a dedicated CGC account - If you do not have or do not wish to register using an external account, you can create a new account on the CGC using a standard email and password.

Password validation

In order to maintain a high level of security and prevent unauthorized access to the Platform, we are checking passwords against a database of commonly used passwords and those that were compromised in data breaches across the Internet, which is why they are considered unsafe. If the password you enter exists in the database, you will need to use a different one. Also, please note that passwords that don't pass the validation are neither stored anywhere in the Seven Bridges system nor linked to your account in any respect.

Additionally, the entire password validation process takes place within the Seven Bridges infrastructure, which ensures an extra level of security as there are no third-party services involved. This mechanism applies when trying to perform the following actions:

  • Sign up for a new account.
  • Set up a new password to replace an expired one.
  • Change your password.

If you are experiencing any other difficulties in setting up or changing your account password, please contact our Support Team.
