Configuring Managed Accounts in SharePoint 2013

What is Managed Account in SharePoint? Why We Need Managed Accounts?
SharePoint uses service accounts for operations such as Farm account, application pools and for service applications. You have to keep a track of all service accounts with their password in a secured file in your system. If the password for any one of those accounts has been changed, the service which uses that specific service account will stop functioning, until you manually update them in SharePoint.

So, The solution comes with SharePoint 2010 and 2013 is you can register your service accounts as a Managed accounts, and you don't have to keep-up the passwords once you register them in your farm and you can manage those managed accounts centrally from SharePoint central administration.

SharePoint centrally stores managed accounts and passwords and it can change the password regularly-automatically, if needed. If there is a password expiry policy set on Active Directory, Then SharePoint automatically detects and changes the password before the scheduled date. (If automatic password change is enabled!). SharePoint also provides Email notification options prior changing the passwords.

In short, Managed accounts are active directory accounts whose credentials are managed by SharePoint
Not all accounts needs to be a managed accounts. E.g. In Search Service Application: Default content access account, which is used to crawl content is usually an un-managed account. Because, when SharePoint changes the password automatically, the content source its crawling may not get that, if its not a SharePoint content source.

How to Create a New Managed Account in SharePoint 2010/2013:

Before creating a managed account, They must be already created in your Active directory and you should create Managed accounts before provisioning web applications and service accounts, as you'll be prompted to choose managed account while creating a web application or service application. To create a new managed account with Central Administration, follow these steps:
  1. Go to Central Administration, Click Security >> Click on Configure Managed Accounts.
  2. Click the Register Managed Account link to create a new managed account.
  3. Enter the Service account's AD user name in domain\username format. Specify the account's password.
  4. If you want SharePoint to automatically change this account’s password on a regular schedule, check the "Enable Automatic Password Change" check box and specify when to change password in accordance to the password expiry policy of your AD.
  5. Check the "Start Notifying By E-mail" check box and specify the number of days before the password change you want to be notified.
  6. Specify the schedule for your password change. You can change the password weekly or monthly.
    You should set changes to occur during scheduled downtime or during light usage, because the password changes will cause momentary service interruptions as application pools are restarted.
  7. Click OK to save the new managed account.
SharePoint sends password change notifications to a single email address, which can be configured via Under: Security >> Configure Password Change Settings >> Notification E-Mail Address.
