With zero-trust policies, you can require that users log in to certain applications with specific types of multifactor authentication (MFA) methods. For example, you can create rules that only allow users to reach a given application if they authenticate with a physical hard key.
This feature is only available if you are using the following identity providers:
- Azure AD
To enforce an MFA requirement to an application:
On the Teams dashboard, navigate to Access > Applications.
Navigate to the Rules section of the application.
If your application already has a rule containing an identity requirement, find it and click Edit.
Add a Require action to the rule.
Select Authentication Method and choose
mfa - multiple-factor authentication.
- Save the rule.
Adding authentication methods into the JWT
Certain identity providers can also share the multifactor authentication (MFA) method presented by the user to login. Cloudflare Access can add these values into the JWT and force. For example, if the user authenticated with their password and a physical hard key, the identity provider can send a confirmation to Cloudflare Access.
Cloudflare Access then stores that method into the same JWT issued to the user.
