Hi Frank, Sorry for late response. SecurityCredentialsProvider is not used in Ignite code because Ignite doesn't provide any implementations of SecurityProcessor out of the box. If you want to make your cluster secure, you need to implement it and configure as a part of your own custom plugin. There are also 3rd party solutions like GridGain that provide such implementations as paid offerings.
