Problem: Getting “The sign-in name or password does not match one in the Microsoft account system” Error in SharePoint Online.
I’ve experienced this error in SharePoint Online PowerShell scripts a couple of times. This could happen in any PowerShell method like CSOM, SharePoint Online Management Shell, or PnP PowerShell. Here are the possible causes and solutions:
- Your user name or password could be wrong (Obviously!). Check if you are able to log in using a web browser with the user name and password given in the PowerShell script.
- Your password may be expired, or your account may be locked out or disabled.
- Your saved password in the Windows credentials store could be incorrect or expired (especially when you use PnP PowerShell module Connect-PnPOnline to get credentials from the Windows Credentials store)
- Your account may be MFA (Multi-factor authentication) enabled! If yes, either MFA must be turned OFF or you have to follow the methods described in How to Connect to SharePoint Online with MFA-enabled accounts from PowerShell?
- When you are working with multiple tenants, make sure the supplied credentials are matching the given URL. E.g. If you are trying to connect to https://crescent.sharepoint.com, make sure you are providing [email protected] (or whatever is appropriate!) but not “[email protected]” in SharePoint Online.
- Instead of using the User name and password, you can use App ID & Password: How to Connect to SharePoint Online using AppID and AppSecret in PnP PowerShell?
- Last but not least: You may have a conditional access policy setup in your environment! Exclude your user account from it.
