Enforce sms as MFA on certain condition

We have turned on SMS and OTP based MFA in out application. We want to enforce SMS MFA during login on some condition. I know we can enforce MFA through actions but it asks user to select any MFA method enabled for the tenant. Is there a way, we could restrict SMS based MFA for certain users for login?

Hi @rajivk ,

Thank you for posting this topic on the Auth0 Community!

This FAQ described how to enforce MFA for a subset of users. To enable SMS, please replace any with SMS in the scripts.

Hope this helps!

Hi @lihua.zhang

We already tried it. Here is the error

I guess, valid values for provider are any, duo, guardian or google-authenticator. Customize Multi-Factor Authentication Pages

You are right @rajivk ! There is no option to set up the provider as sms only.
