signin and password does not match

Question

I'm trying to connect to SharePoint Online but I'm getting this error and not 100% sure why so I would be really appreciated if I can get any help or suggestion why it might be.

I believe it might have to do with my tenant using MFA so just wondering how can I connect/login using MFA?.

   #Variables  
   $SiteURL = "https://companyName-my.sharepoint.com/personal/yzqpsn_nam_corp_m_com"  
   $ServerRelativeUrl= "documents/Testing"  
      
   Try {  
       #Get Credentials to connect  
       $Cred= Get-Credential  
      
       #Setup the context  
       $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)  
       $Ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)  
        
       #Get the web from URL  
       $Web = $Ctx.web  
       $Ctx.Load($Web)  
       $Ctx.executeQuery()  
      
       #Get the Folder object by Server Relative URL  
       $Folder = $Web.GetFolderByServerRelativeUrl($ServerRelativeUrl)  
       $Ctx.Load($Folder)  
       $Ctx.ExecuteQuery()  
      
       #Call the function to empty Folder  
       Empty-SPOFolder $Folder  
      
       #Delete the given Folder itself  
       Write-host  -f Green "Deleting Folder:"$Folder.ServerRelativeUrl  
       $Folder.Recycle() | Out-Null  
       $Ctx.ExecuteQuery()  
   }  
   Catch {  
       write-host -f Red "Error:" $_.Exception.Message  
   }

Hi @Aase Nomad
You could using the following cmd to connect to SharePoint Online with MFA:

#Add required references to OfficeDevPnP.Core and SharePoint client assembly  
[System.Reflection.Assembly]::LoadFrom("C:\Program Files\WindowsPowerShell\Modules\SharePointPnPPowerShellOnline\3.29.2101.0\OfficeDevPnP.Core.dll")   
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client")  
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client.Runtime")  
   
$siteURL = "https://contoso.sharepoint.com/sites/siten_name"  
    
$AuthenticationManager = new-object OfficeDevPnP.Core.AuthenticationManager  
$ctx = $AuthenticationManager.GetWebLoginClientContext($siteURL)  
$ctx.Load($ctx.Web)  
$ctx.ExecuteQuery()  
    
Write-Host "Title: " $ctx.Web.Title -ForegroundColor Green  
Write-Host "Description: " $ctx.Web.Description -ForegroundColor Green

with MFA you have to use interactive (or web login). In addition to CSOM you may use PnP.PowerShell which contain large set of ready cmdlets for various tasks related with SPO. Interactive login with PnP.PowerShell will look like that:

Connect-PnPOnline -Url $url -Interactive
