update credentials via command line or api

This is al the info I could find and it says it applies to SNMP credential and WMI discovery credentials. You should try to see if it works for WMI stored credentials:

github.com/.../Credential-Management

Thanks for digging this up!   Theoretically, I'm thinking you could use this with a tool designed to manage rotation of PWs.
have 2 sets of creds per function (i.e. wmi for general polling - i.e. #monitor1 and #monitor2)
when change required, user 2 gets enabled and pw gets changed by tool, and command and control script (C&CS) grabs / tool kicks off with username and new pw in parameter.
C&CS uses api to update monitoring user 2, then C&CS updates all nodes/apps with credentials for user1 to user2
C&CS then disables user2 after some hold down time.

don't have time to work on this now, but need is pressing so hopefully, soon.

edit: idea of 2 creds per was gotten from https://thwack.solarwinds.com/product-forums/network-performance-monitor-npm/f/forum/89228/when-you-have-to-change-all-passwords-for-the-orion-monitoring-platform
