 ### Authenticated flow
-By requiring a user to authenticate on the initiating device with a phishing resistant authentication method before initiating a cross-device flow, the server can prevent an attacker from initiating a cross-device flow and obtaining QR codes or user codes. This prevents the attacker from obtaining a QR code or user code that they can use to mislead an unsuspecting user. This requires that the initiating device has sufficient input capabilities to support a phishing resistant authentication mechanism, which may in itself negate the need for a cross-device

 ### Practical Mitigation Summary
 The practical mitigations described in this section can prevent the attacks from being initiated, disrupt attacks once they start or reduce the impact or remediate an attack if it succeeds. When combining one or more of these mitigations the overall security profile of a cross-device flow improves significantly. The following table provides a summary view of these mitigations:
