Connect-PnPOnline: The sign-in name or password does not match one in the Microsoft account system.

Question

Hello, I am trying to connect to SharePoint via Connect-PnPOnline. When I add my credentials for the SharePoint url in Windows Credential Manager and I type

Connect-PnPOnline -Url https://<domain>.sharepoint.com

everything works fine. However when I try the same with the following script

$username="<username>"
$encpassword = convertto-securestring -String "<password>" -AsPlainText -Force
$url = "https://<domain>.sharepoint.com/"
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $encpassword
Connect-PnPOnline -Url $url -Credentials $cred

It fails with the error message "Connect-PnPOnline : The sign-in name or password does not match one in the Microsoft account system."

Any idea why it's doing it? I am trying to write a script that connects to SharePoint and reads a file, without user interaction.

Thank you

Hi there,

Here are the possible causes and solutions for your issue.

-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)
-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.

Hi @Panos Konstantinidis ,

Please try to do a troubleshooting:

1. Please ensure that the username and password are correct.
2. Please check if the account with multi-factor authentication (MFA).

If your account with multi-factor authentication (MFA), your script will not work. You can use the following methods to connect to SharePoint Online:

1.Method 1:

Connect-SPOService -Url https://YourTenant-admin.sharepoint.com  

2.Method 2:

#Site Variables  
$SiteURL = "https://crescent.sharepoint.com"  

#Connect to PnP Online  
Connect-PnPOnline -Url $SiteURL -UseWebLogin  

3.Method 3:

#Site collection URL  
$SiteURL = "https://crescent.sharepoint.com"  

#Connect to SharePoint Online with AppId and AppSecret  
Connect-PnPOnline -Url $SiteURL -ClientId "xxxxxxxx" -ClientSecret "xxxxxxxx"
