Any way to enable the MFA while using external DB as user storage

Hi, i am new to Auth0, i have one question regarding the external DB and MFA.

Any way to trigger the MFA while using external DB as user storage?

Hi @zhiwei , welcome to the Auth0 Community!

Yes you can still trigger and use MFA with the External User Database.
To do this, you could look to trigger MFA by using a Post Login Action and you could get the user profile data to make decisions based on the user profile as to when/what MFA to trigger. You can see an example here of the user profile returned with the login script.
Hope this helps, thanks!

i will go through these documents.

thx a lot.
