Application Using Device Code Authentication Flow

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.

Applications That Are Using ROPC Authentication Flow

Resource owner password credentials (ROPC) should be avoided if at all possible as this requires the user to expose their current password credentials to the application directly. The application then uses those credentials to authenticate the user against the identity provider.
