Edge and azure Password-Based SSO

@Kjetil Jarstein
It is an expected behavior. On first attempt, users will be prompted to install the Microsoft Authenticator on iOS or the Intune Company Portal on Android.
Thereafter, you will be able to make use of SSO on the Edge Browser.

Here's a blog that would help you understand and configure the steps to enable the same - https://techcommunity.microsoft.com/t5/Enterprise-Mobility-Security/Microsoft-Edge-on-iOS-and-Android-now-supports-conditional/ba-p/476091

Hello @neray-MSFT , and thank you for the answer. I see now after spending some time on this matter that the question is a bit unclear.

To address what you write above, these are client devices registered in Intune using the company portal and both of the devices have Authenticator set up. We have created policies making the users use Edge instead of the Intune Managed Browser.

What I have seen now, is that on Android and iOS devices, trying to open an Enterprise application (those found in MyApps (aka The Access Panel)) through the "old" MyApps portal, myapps.microsoft.com and having them set up with password-based SSO in Azure, it works as expected. The users get prompted for username and password (and any other field found on the login page of the web-page). But when I try the same thing using the newer myapplications.microsoft.com portal, I get redirected to download the Intune Managed Browser every time, on both platforms.

On windows 10 it works fine independent of browser and portal as long as I have added the Secure Sign In extension.
