A:
Go to following:
Central Admin – Security – Configure Service Account – General Security – Configure Managed Account
Then edit the managed account that corresponds to your application pool. You will have an option to change the password on the edit page.
You can also do the same with a Powershell command named: Set-SPManagedAccount.
