We detected that this browser or OS does not support FIDO2 security keys. error received on all hybrid domain computers just recently; even computers that have keys installed at an earlier date

Question

Setting up alternate MFA for end users who don't have phones. This week, the feature of adding a FIDO2 security key ends with this error window:

Multiple people already have keys and are using them. However, any new keys I attempt to activate fail with this error.

Answer 1

Here are a few steps you can take to troubleshoot and resolve this issue:

Verify browser and OS compatibility: Ensure that the browsers being used on the affected computers support FIDO2 security keys. FIDO2 is supported by modern browsers such as Google Chrome, Microsoft Edge, Mozilla Firefox, and others. Check the browser versions and update them if necessary. Additionally, verify that the operating system on the computers meets the minimum requirements for FIDO2 support.

Check for driver or firmware updates: FIDO2 security keys may require driver or firmware updates to function properly. Contact the vendor or manufacturer of the security keys and check for any available updates. Install the latest drivers or firmware on the affected computers and try activating the keys again.

Test with different browsers and computers: If possible, try activating the FIDO2 security keys on different computers with different browsers. This can help identify if the issue is specific to certain computers or browsers. It's also worth testing on a known-working computer to rule out any issues related to the security keys themselves.

Contact Azure Support: If the issue persists and you have verified browser and OS compatibility, it's recommended to reach out to Azure Support for further assistance. They can help investigate the issue in more detail and provide guidance specific to your Azure environment.

It's important to note that FIDO2 security keys are just one option for multi-factor authentication (MFA). If the issue persists, you may consider exploring alternative MFA methods, such as phone-based authentication apps or hardware tokens that are compatible with the affected computers.

I hope these steps help you resolve the issue. If you have any more questions, feel free to ask!

Answer 3

We have the same issue at our end and it's a Microsoft Azure issue but don't know the answer yet. We've been doing Fido2 keys registration since Monday May 29th, 2023 without issues until Wednesday May 31st but on June 1st, something changed on Microsoft side because and we've been getting the browser and OS not supported message for regular users without any privilege's.

If you are a user or IT staff with some kind of Azure admin permissions, there are no issues doing Fido2 keys registration. The errror message comes up right after choosing the Security key option and you don't have the option to choose between USB of NFC so it's not a driver of firmware issue and this happens with Chrome, Edge and Firefox.

I've done some testing on my computer and other computers with my account and have no issue but with a regular user account I get the error message within the same session. OS version and browser versions all meet the minimum requirements.

We have opened a support case with Microsoft and we hope to have this issue solved by the end of next week.

Answer 4

Support contacted me and said they are rolling back the most recent update and that we should see a resolution in an hour or two for those systems currently connected.

Since we have a lot of places our end users use their computer it may take longer.

I'm just happy it wasn't something I overlooked! ;-)

Answer 5

Thanks for the response.

I have tested different computers including ones that I installed keys on at an earlier date.

The environment is stable and up to date with OS, browser, office, etc…

I guess it’s off to Azure support
