Hi @Saida SADIKI,

Thank you for posting in this community.

First, I would like to confirm with you about how you created your Credentials.

Let me give you an example here:

$SiteURL="https://domain.sharepoint.com/sites" 
$UserName="******@domain.onmicrosoft.com" 
$Password = "userpassword"   
$SecurePassword = ConvertTo-SecureString -String $Password -AsPlainText -Force 
$Cred = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist $UserName, $SecurePassword  
try{ 
#connect to sharepoint online site using powershell 
Connect-PnPOnline -Url $SiteURL -Credentials $Cred  
write-host "Connect successfully" -foregroundcolor green 
}catch{  
write-host "Error: $($_.Exception.Message)" -foregroundcolor Red  
}

a

Thank you for your time and efforts in advance.
