How to configure two factor authentication for a particular site (subsite) in SharePoint Online

    Question

  • I need to implement two factor authentication only for a sub site in SharePoint online. Users would be given permissions to the website, however we need to have them authenticate again by phone (or other form) before giving the access. I have gone through setting up the MFA in Office 365 but I don't want the users to go through MFA each time they login, instead only when they access this particular site. I am also ok with any custom approach to achieve this - like generating a cookie upon login and check upon the cookie on each request to the site. Please suggest.

  • You cannot get that granular unfortunately, it will be enabled for all SPO sites.

  • You would have to setup a new farm and implant that site address into your current farm to achieve your goal of this.

  • Can it be done using any custom development like generating an auth cookie while accessing the site and check if it is present and redirect to the login page.
