Who are you?
With a secret, nobody else can join as you: type the same name and secret next time, on any computer, and your character setup comes back. The secret is never saved or shown: the server keeps only the tag made from it. Make it long; short ones can be guessed.

The tag comes from your secret, so only you can have it. Without one, this browser keeps a tag of its own: another computer, or clearing this browser's data, means a new tag and a fresh character.
