Managed Accounts in SharePoint

One of the Best features of SharePoint 2010 is the introduction of Managed Accounts concept. Earlier in MOSS 2007, changing the password is bit painful job especially when the service accounts passwords got expired. 

Now, Admins can easily maintain the passwords at central location in central admin app and need not change the password everywhere on SharePoint. 

Once we register service account as Managed Account, We need not enter or remember the password for this account when configuring the the account for any Web app  or Service application.

You need to have Active Directory permissions to change the passwords for the Managed Accounts
