How Do I Connect My GitHub and Bitbucket Accounts on CircleCI?

Prerequisites:

If you have already signed up to CircleCI with one of your VCS accounts, or have linked them to another account, then you will be unable to link them immediately. You will need to reach out to CircleCI Support to have them unlink your accounts: https://circleci.zendesk.com/hc/en-us/requests/new

To connect your GitHub and Bitbucket accounts on CircleCI:

1. Log in with your primary account (e.g. GitHub)
2. Click your avatar icon (bottom-left of the CircleCI UI) or go to https://app.circleci.com/settings/user 

On the next screen, click the "Connect" button:

• If you are not already logged into your secondary VCS account, you'll be redirected to the VCS website to authenticate and authorize CircleCI.
• If you are already logged into your secondary VCS account, it will be added to your existing CircleCI account.

Once this is done, the "organization picker" will also list the organizations available to the secondary VCS account.

Next to each organization's name you'll see either a GH or BB badge indicating whether an organization is associated with GitHub or Bitbucket.
