Problem:

I would like to link my existing DataCamp account to LinkedIn, Google or Facebook. 

Background:

You signed up initially for a DataCamp account directly with your email address. You would now like to switch your login method to LinkedIn, Google or Facebook account.

Solution: 

For the purposes of this article, we'll review LinkedIn, but the process is largely the same for Google and Facebook. Here’s how you can connect your LinkedIn account to DataCamp:

1. Log in to your DataCamp account
2. Navigate to Account Settings/ Social
3. Click on the Link LinkedIn Button
   
   
   
   
4. If you’re not logged into an account on linkedin.com, then you’ll need to enter your login credentials. If you’re already logged into that specific LinkedIn account on linkedin.com, you’ll just need to authorize DataCamp to use your account. 
   
5. Click on "Allow" 

All done! You can now sign in with LinkedIn without any hassle.
