description: |
|
|
Device code flow is an OAuth 2.0 protocol flow specifically for input constrained devices and is not used in all environments.
|
|
If this type of flow is seen in the environment and not being used in an input constrained device scenario, further investigation is warranted.
|
|
This can be a misconfigured application or potentially something malicious.
