Quick Post here. In my test enviro I tested Changing the farm admin password (case 2) but only recovered my SharePoint FE in test, which actually lead to case 1. Here it is:

Source of info: How to Change SharePoint Farm Account Password using PowerShell? – SharePoint Diary

Case 1: Farm Account’s Password is already changed in Active Directory

I don’t know why he mentions using the CA when the CA won’t work when the farm account is used for that service, in that case use Powershell:

#Get the Farm Account
$FarmAccount = Read-Host "Enter the Farm Account in Domain\User Format:"
  
#Get the changed Password for the farm account
$Password = Read-Host "Enter the changed password for Farm Account" -AsSecureString
  
#Update the password for farm account
Set-SPManagedAccount -Identity $FarmAccount -ExistingPassword $Password -UseExistingPassword $true

Case 2: Change password for SharePoint Farm Account

UI Way:

• Go to your SharePoint Central Administration site >> Click on Security >> Configure Managed Accounts
• Click on “Edit” icon next to the SharePoint Farm account.
• Tick “Change password now” check box and enter the new password by setting “Set account password to new value” option
• Enter the new password and click on OK to change the password of SharePoint farm account.

Or PowerShell:

#Get the Farm Account
$FarmAccount = Read-Host "Enter the Farm Account in Domain\User Format:"

#Get the changed Password for the farm account
$Password = Read-Host "Enter the New password for Farm Account" -AsSecureString

#Update the password for farm account
Set-SPManagedAccount -Identity $FarmAccount -NewPassword $Password -ConfirmPassword $Password
