Can I use my social account to sign in?

Before you can sign in with your social account, you will need to enable Social Sign-in.

To do this, sign in using your normal email address and password, then you should navigate to the Edit profile section (using the dropdown in the top right-hand corner of iDEA). 

Then click on 'Manage Social Sign-in' to click on the relevant social account(s) you want to link up to your iDEA account.
