---------------------------------
bq. 1. Maybe change passwords to use concurrentHashMap and use read/write lock
guard nextMasterKey/currentMasterKey for better concurrency as this is a chatty

DONE
bq. 2. Put In the same line
DONE
bq. 3. Info level for easier debugging, while stabilizing this feature.
