Answer 2

Hello @H Raja,

Thank you for posting your query on Microsoft Q&A.

The document you are referring to is correct. It states that a single user account can have up to 10 security keys (e.g., YubiKeys). There are no other documents or limitations beyond this. In Entra ID, a single user account is limited to a maximum of 10 security keys.

I hope this information is helpful. Please feel free to reach out if you have any further questions.
