The Nacos community recently released versions 2.2.0 and 2.2.1, which brings significant changes to the default authentication plug-in. However, because the default token.secret.key is used in the default console UI of Nacos, many users who deploy images or use the latest version by default experience a high number of startup failures after the token.secret.key default value is removed. This greatly affects the usability of the users. Therefore, version 2.2.2 is mainly optimized to address this problem.
In Nacos 2.2.0 and 2.2.1, three default values related to authentication were removed to avoid the risk of database collision due to unmodified changes during deployment. However, token.secret.key is a mandatory dependency for the landing page of the default console UI of Nacos. As a result, many environments that use the default configuration or have lower security requirements cannot be started and run directly, causing trouble for a large number of users.
Therefore, the main change in version 2.2.2 is the removal of the mandatory dependency on token.secret.key by removing the login requirement in the default console without authentication. If authentication is enabled, users still need to set custom token.secret.key, nacos.core.auth.server.identity.key, and nacos.core.auth.server.identity.value. Otherwise, the node cannot be started and the login and authentication will fail.
For more information about the specific changes in version 2.2.2, please refer to the change log.
