The auth system to use, currently only 'nacos' is supported:

nacos.core.auth.system.type=${NACOS_AUTH_SYSTEM_TYPE:nacos}

The token expiration in seconds:

nacos.core.auth.default.token.expire.seconds=${NACOS_AUTH_TOKEN_EXPIRE_SECONDS:18000}

The default token:

nacos.core.auth.default.token.secret.key=emhhb2JlbnNodWFpdGVzdG5ld2tleWluZm9sb25nZW5vdWdoCg==

Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.
