1 - About

A token is a authentication method

The concept behind using tokens is that you can authenticate to a central authority and then have permissions granted to a separate system without needing to give that system your credentials.

If the server providing the service was compromised, credentials would still be safe, and the attacker would only have access to resources until the token expired. Hence tokens are generally short lived.
