What supports modern authentication in Microsoft 365

I get a lot of questions of what does and doesn’t support pure modern authentication in Microsoft 365. Pure modern authentication DOESN’T include App Passwords!

In short, you are best off with the latest version of the Microsoft software. However, here’s the list:

Office 2016

Modern authentication is already enabled for Office 2016 clients, you do not need to set registry keys for Office 2016.

Office 2013

To enable modern authentication for any devices running Windows (for example on laptops and tablets), that have Microsoft Office 2013 installed, you need to set the following registry keys. The keys have to be set on each device that you want to enable for modern authentication:

Registry key        Type        Value

HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\EnableADAL        REG_DWORD        1

HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\Version        REG_DWORD        1

iOS

In order to use the native iOS mail client, you will need to be running iOS version 11.0 or later to ensure the mail client has been updated to block legacy authentication.

Mac

One of the three most recent versions of macOS. When a new major version of macOS is released, the macOS and the previous two versions.

macOS Mail on macOS < 10.14 does not support Modern Authentication

Android

Android (Google) Mail does not support Modern Authentication

Outlook on mobile

Outlook for Mobile supports modern authentication by default

Office for iPad® and iPhone® (including Outlook for iOS on iPad® and iPhone®) requires iOS 12.0 or later. Office for iPad Pro™ requires iOS 11.0 or later Office is supported on the two most recent versions of iOS.

Office for Android can be installed on tablets and phones running any of the supported versions of Android and have an ARM-based or Intel x86 processor. Starting on July 1, 2019, support will be limited to only the last four major versions of Android.

Office for Android™ can be installed on tablets and phones that meet the following criteria: running Android KitKat 4.4 or later version and have an ARM-based or Intel x86 processor.

One thought on “What supports modern authentication in Microsoft 365

  1. I would like to add the following based on what I’ve seen with our clients:

    • Recent versions of the Samsung mail app that comes with the Galaxy S and Galaxy Note series do support modern authentication. Your mileage may vary with others.
    • iOS tends to have issues with multiple re-prompts for password when first setting up O365 mail with modern authentication. Rebooting often helps.
