+You can create a separate IDP app with a custom MFA flow. For example, with

+2. Use the same IDP app for MFA:
+
+Some IDPs provide a way to fork to different flows using the same IDP app.
+For example, with Okta (OIDC), you can provide `acr_values: ["phr"]` to

-Teleport does not make any assumptions as to how the MFA app is configured.
-If desired, you could even use your basic login flow with username, password,

+For a simpler approach, you could use the same IDP app for both login and MFA
+with no adjustments. For Teleport MFA checks, the user will be required to
+relogin through the IDP with username, password, and MFA if required.
