Changing the Action Account Password - SCOM 2012R2

For 2012R2, is this really as simple as going to Administration/Run As Configuration/Accounts and selecting theAction Account credentials and changing the password there??

As long as the change matches what is in AD, then all should just keep working OK? Or is there a bit of "back-end" housekeeping to look after as well, as in the old 2007R2?

Thx,

JB
