Error while registering Security Key (FIDO2) – “We’re sorry, we ran into a problem” with Correction ID

Hi Team,

I am trying to register a Security Key (FIDO2 – Yubico Security Key NFC Type-A) under My Security Info (aka.ms/mysecurityinfo), but I keep getting the following error popup:

“We’re sorry, we ran into a problem. Please choose ‘Next’ to try again.”

The error message shows:

• Correlation ID: 6bac8660-e6d4-4be4-9ceb-affb2ffda117
• Timestamp: 2025-11-14T08:08:07.45Z

I have already tried:

Using a different browser (Edge/Chrome)

Using an incognito window

Removing and re-adding the key

Trying from another PC

Checking if FIDO2 is enabled in Azure AD

Checking Authentication Methods policy

Ensuring the key is not previously registered

Still, the same issue occurs.

What I want to confirm:

Is this error related to a tenant policy, Conditional Access, or Authentication Methods policy?

Do I need to enable any extra settings under:

Azure AD → Security → Authentication methods → FIDO2 Security Key

  **Azure AD → Devices → Device settings**
1. Does Microsoft see any backend failure related to my **Correction ID**?

Is this a known issue with YubiKey Security Key NFC Type-A on certain tenants?

What steps should I follow to resolve this?

Please help me understand what is causing this registration failure and how to fix it.
