Hi All,

Greetings for the day!!! Today new issue and solution !!!

Use Case / Background

  • We need to connect one of our SharePoint site in our tenant
  • Though we can use Connect-SPOService and Get-SPOSite but we are using PnP CMDLETs since for further operations its easy with PnP Online
  • So we are using Connect-PnPOnline CMDLET to connect to our SiteCollections
  • We are connecting with our UserName and Password
  • While connecting to our SharePoint site with Connect-PnPOnline CMDLET with correct user name and password but then we are getting an error – error validating credentials

Connect-PnPOnline -Url https://knowledgejunction1.sharepoint.com/demoremoveuserpermissions

  • The above CMDLET prompt for user name and password and we were sure that we entered correct user name and password

Issue / Error :

Connect-PnPOnline : AADSTS50126: Error validating credentials due to invalid username or password.
Trace ID: b49df603-9ccc-4d49-be1e-803b51431501

  • Connect-PnPOnline
  • ~~~~~
    • CategoryInfo : NotSpecified: (:) [Connect-PnPOnline], MsalUiRequiredException
    • FullyQualifiedErrorId : Microsoft.Identity.Client.MsalUiRequiredException,PnP.PowerShell.Commands.Base.ConnectOnline

fig : Microsoft 365 – Connect-PnPOnline – exception while connecting to site, this exception is because MFA is enabled for the current user

Cause / Why such issue

  • This is the error because we are connecting the site with user which has “multi-factor authentication” enabled
  • So when we have multi-factor authentication is in place for users and we try to do normal connection we get an issue / error

Solution

  • To avoid this error we can connect with either of following two parameters
    • UseWebLogin
      • With this parameter we connect to SharePoint site using cookie based legacy authentication
      • With this type authentication we are limited to few functionality
      • We can not use GRAPH APIs with this type of authentication
      • Also few functionality related to provisioning templates like – Get-PnPSiteTemplate, Get-PnPTenantTemplate, Invoke-PnPSiteTemplate, Invoke-PnPTenantTemplate can not be used
    • Interactive
      • With this parameter we connect to SharePoint site and can use GRPAH APIs as well
      • Basically it connects to Azure AD and acquires access token
Connect-PnPOnline -UseWebLogin -Url 

Connect-PnPOnline -Interactive -Url
