Is the quota for ClientLogin is 50,000 calls per day?

I know when you use OAuth to authenticate you're project has a 50,000
call per day limit. What about ClientLogin? How many APIs calls are
you allowed to make per day when using ClientLogin?

50,000, because quota is based of the developer key you must send with each request to the API. It's not based on the authorization method.

With OAuth 2, the access token is used to send this ID.

With Client Login, you must append the key as a query parameter to each API request.
