Connect to SFBO PS using MFA enabled Administrator account

So my administrator account was enabled for MFA as a part of additional security and with the MFA enabled account, connection to the Skype for business online PowerShell module was failing with below error:

PS C:\WINDOWS\system32> $session = New-CsOnlineSession -Credential $cred -Verbose
VERBOSE: Determining domain to admin
VERBOSE: AdminDomain = ‘’
VERBOSE: Discovering PowerShell endpoint URI
VERBOSE: TargetUri = ‘’
VERBOSE: Requesting authentication token
Get-CsWebTicket : Logon failed for the user ‘’. Please create a new credential
object, making sure that you have used the correct user name and password.
At C:\Program Files\Common Files\Skype for Business
Online\Modules\SkypeOnlineConnector\SkypeOnlineConnectorStartup.psm1:107 char:18
+ … webticket = Get-CsWebTicket -TargetServer $TargetServer -Credential $ …
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Get-CsWebTicket], CommonAuthException
+ FullyQualifiedErrorId : Microsoft.Rtc.Admin.Authentication.CommonAuthException,Microsoft.Rtc.Management.OnlineConnect

With the same credentials, i was able to login to the portal but following the error, i changed the password but got same error. So i logged a ticket with Microsoft and Nitin from Microsoft gave me a clue that worked.

Here’s how the issue got solved.

  1. Login to the O365 portal
  2. navigate to “View your account” and then “Security and Privacy”
  3. Click on “Additional Security verification”
  4. Now click on “Update your phone numbers used for account security”.  A new window will open, taking you to address.
  5.  Navigate to “app passwords” tab
  6. Here’s the page where you can create application passwords. Create an app password, save it at secure place as the password is a random number and you do not have privilege to set password of your choice.
  7. With this password, you would be able to connect to the Skype for business online powershell.
