Verified accounts are given to celebrities by Twitter to prove that they are the real celebrity and not a fake account. It makes it easier for fans to make sure they are following who they think they are, and to help keep them safe on the internet. A verified Twitter account is an account that Twitter has confirmed to be the real person. It's only really celebrities that have verified accounts. So, if you see a celebrity with the blue verified check mark then you know that the account belongs to the real celebrity and not an impersonator.
