Hello,

i setup MFA on my ADFS server. I modify Adfs theme for proofup page: https://github.com/MicrosoftDocs/windowsserverdocs/blob/master/WindowsServerDocs/identity/ad-fs/operations/configure-ad-fs-and-azure-mfa.md .

In chrome it works just fine, but in Microsoft EDGE users are getting this: Error details: The selected authentication method is not available. Choose another authentication method or contact your system administrator for details.

My WIASupportedUserAgents are:

("MSIE 6.0", "MSIE 7.0; Windows NT", "MSIE 8.0", "MSIE 9.0", "MSIE 10.0; Windows NT 6", "Windows NT 6.3; Trident/7.0", "Windows NT 6.3; Win64; x64; Trident/7.0", "Windows NT 6.3; WOW64; Trident/7.0", "Windows NT 6.2; Trident/7.0", "Windows NT 6.2; Win64; x64; Trident/7.0", "Windows NT 6.2; WOW64; Trident/7.0", "Windows NT 6.1; Trident/7.0", "Windows NT 6.1; Win64; x64; Trident/7.0", "Windows NT 6.1; WOW64; Trident/7.0","Windows NT 10.0; WOW64; Trident/7.0", "MSIPC", "Windows Rights Management Client", "=~Windows\s*NT.Edg.")

Where is the problem, thanks a lot guys

    Hi @HanakJ :

    Reviewed your WIASupportedUserAgents output, noticed there could be issue with user agent for Edge browser.

    Refer to this article https://learn.microsoft.com/en-us/windows-server/identity/ad-fs/operations/configure-ad-fs-browser-wia and update the user agent as it is mentioned here.

    If the above article doesn't help, can you help me with the output & screenshot of this command from your ADFS server. "Get-AdfsProperties | select -ExpandProperty WiaSupportedUserAgents"

    Proofup wasnt initiazed, because the error code did not meet the condition. I had to change json to "The selected authentication method is not available".

    I found this there: https://www.reddit.com/r/sysadmin/comments/lq5djs/adfs_and_azure_mfa_onloadjs_not_catching_proof_up/
