Identification isn't authentication. A public client can identify itself for the purpose of providing user context, statistics, etc.

Can anyone please help me understand how these two sentences do not contradict?

>From section 2.2 Client Identifier
The client identifier is not a secret, it is exposed to the resource owner, and MUST NOT be used alone for client authentication.

>From section 3.2.1 Client Authentication
A public client that was not issued a client password MAY use the client_id request parameter to identify itself when sending requests to the token endpoint.

Thanks.
