Why use login? and not just /auth

[jackkitley]

Sorry but just had a question regarding the API.

I see that there is /auth and then /login. I use the auth request to get a token and expiry date but then do a login after the auth request to get the users details.

Why would i want to use the /login if i was already authenticated from the /auth request? In the auth request i can return the user details.

If there is a reason then i would love to know why.

Thanks
