Plex Accounts
A Plex account is basically your personal identity for things associated with Plex. You use it to sign in to the plex.tv website, the support forums, and Plex apps.
The Plex website will allow you to manage your Plex account. You can use the top menubar on the plex.tv website to sign in, sign up for a new account, or access account information if already signed in.

Setting a Username
When an account is created a default username is created by taking half of the first part of the email address and appending numbers until it’s unique. If you wish to create a username you can do that on your account page. Link: Plex Web App: Account page
