How would you like to sign in?
Not sure? Most people pick "Create a new CCA account" below.
We make you a username and password to sign in with. Your username will look like yourname@ccauser.com. Pick this if you are not sure — it is the simplest option and works for most people.
Sign in with an account you already have through an SSO provider — for example, Okta, Microsoft Entra ID, Google Workspace, or another SAML identity provider you run or pay for. You will need the SAML metadata URL for that provider, and you must control the domain you want to sign in with. Pick this only if you already know what SAML and SSO mean.
Before you continue, please read the privacy notice. We only collect what we need to verify who you are and contact you about your application. We do not create any account until a CCA reviewer approves your submission by hand. For full detail, see how CCA uses participant data.
