Make sure you are on the latest Dynamic alpha packages
In your Dynamic Dashboard, go to the Security page and in the Account MFA section, click on the Authenticator Apps toggle, then click Save Changes
Optionally, you can require users to MFA on signup by clicking on the settings gear to the right of the Authenticator Apps toggle, then toggle on “Require at boarding”
That’s it! Make sure you are using the same environment id from the SDK & API Keys page in your app. When you sign in to your app, you will be prompted to MFA if you toggled on “Require at onboarding”, otherwise you will be able to optionally add MFA from the user profile section of the Dynamic widget.
