token_auth acts as your password and is used to authenticate in API requests. You can find the
token_auth by logging in Matomo (Piwik), then click on Administration in the top menu, then click the link “API” in the left menu.
token_auth is secret and should be handled very carefully: do not share it with anyone. Each Matomo user has a different
token_auth value can be re-generated on request by any user under Administration > Personal Settings.
