I completed setting up SharePoint 2019 using Azure SQL MI, as you would know MI does not accept service account and have to connect to SharePoint using a local sql account. Now the issue I'm facing is the sql account expired, and when I update the pw in sql it takes central administration down. So I need to find a way to update the password in SharePoint too. Can you guys help me?
Use following powershell to update SharePoint service account password:
Set-SPManagedAccount -identity "AzureAD\SA_ManagedAccount" -NewPassword (ConvertTo-Securestring "password-2" -AsPlainText -Force) –SetNewPassword
