+### Enable CAPTCHA feature flag
+
+To enforce CAPTCHA during sign-up, sign-in, or MFA, you need to add a technical profile that enables a feature flag for each scenario, then call the technical profile in the user journey.
+
+1. In the *TrustFrameworkBase.XML* file, locate the `ClaimsProviders` element and add the claims provider by using the following code:
+
+```xml
+<!--<ClaimsProvider>-->
+...
+<ClaimsProvider>
+
+    <DisplayName>Set Feature Flags</DisplayName>
+
+    <TechnicalProfiles>
+
+    <TechnicalProfile Id="SetFeatureDefaultValue">
+        <DisplayName>Set Feature Flags</DisplayName>
+        <Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.ClaimsTransformationProtocolProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
+        <OutputClaims>
+            <OutputClaim ClaimTypeReferenceId="signupCaptchaEnabled" DefaultValue="true" />
+            <OutputClaim ClaimTypeReferenceId="signinCaptchaEnabled" DefaultValue="true" />
+            <OutputClaim ClaimTypeReferenceId="mfaCaptchaEnabled" DefaultValue="true" />
+        </OutputClaims>
+    </TechnicalProfile>
+    </TechnicalProfiles>
+</ClaimsProvider>
+...
+<!--<ClaimsProviders>-->
+``` 
+
+2. Set `DefaultValue` to true or false depending on the CAPTCHA scenario
+
+3. Add the feature flags technical profile to the user journey then update the order of the rest of the orchestration steps.
+
+```xml
+<!--<UserJourneys>-->
+...
+<UserJourney Id="SignUpOrSignIn">
+    <OrchestrationSteps>
+
+        <!--Add this orchestration step-->
+        <OrchestrationStep Order="1" Type="ClaimsExchange">
