Get-CsWebTicket : Failed to logon with given credentials. Make sure correct user name and password provided.

When trying to login to Skype Online through PowerShell or the Skype for Business control panel you receive the following error:
The WinRM client cannot process the request. Basic authentication is currently disabled in the client configuration. Change the client configuration and try the request again.

Or this one:

Get-CsWebTicket : Failed to logon with given credentials. Make sure correct user name and password provided.

Then the search begins, and brought me to this:

View the current winrm settings to check whether "basic authentication" has been disabled or not.

winrm get winrm/config/client/auth

Auth

    Basic = true [Source="GPO"]

    Digest = true [Source="GPO"]

    Kerberos = true

    Negotiate = true

    Certificate = true

    CredSSP = false

For me it was set with a GPO.

Trying to set it with this:

winrm set config/client/auth/ @{basic="true"}

Update:

Set-Item WSMan:\localhost\Client\Auth\Basic -Value 'True'

Error: Invalid use of command line. Type "winrm -?" for help.

That didn't go as planned.

The tried to set it in the registry with this:

Open regedit as admin and go to:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WinRM\Client

Simply change the DWORD from 0 to 1 and then restart the PowerShell console

Well that's nice but no solution.

Then searched for the other error, the one with the Get-CSWebTicket error.

Which led me to this:

Since Skype for Business Control Panel don’t support two-step verification we will need to to set up an “app password” for our Office 365 admin account that has MFA enabled.

Oh, really...and yes I just enabled the force MFA option policy in Azure: "Baseline policy: Require MFA for admins (Preview)".

Created an app password an pasted it in my SkypeOnline PowerShell module and voila I was in once again.
