VIDEO – Disable Legacy Auth & Connect PNP
Even with Legacy auth disabled, you can successfully run Connect-PNPOnline. Video demo shows changing SPO tenant security, then how to register new AppId for Connect-PNPOnline access to all site collections in tenant. The “AppRegNew” and “AppInv” ASPX pages can be used to establish authentication channel for PowerShell work in PNP on Office 365 tenants where Legacy Auth is disabled. Cheers!
