Hi @Cat Daddyx2 , unfortunately Security Center does not recognize third party applications such as DUO.
Security Center's MFA recommendations don't support third-party MFA tools (for example, DUO).
If the recommendations are irrelevant for your organization, consider marking them as "mitigated" as described in Exempting resources and recommendations from your secure score. You can also disable a recommendation.
If this answer helped you, please mark it as "Verified" so other users may reference it.
Thank you,
James
