SharePoint 2013–Update password of a managed account using PowerShell

We can change the password of a SharePoint managed account from SharePoint central administration console as well as using PowerShell.

Fun fact here is that, we don’t need to do anything from our Domain Controller. When we update the password either from Central Administration or PowerShell, it will automatically update the user’s password in Active Directory.
