How to use chrome to login to same site twice with different credentials ?

Even though it runs tabs as different processes it appears to not support this... any ideas / documentation I might have missed ?

• Try two different incognito windows.

  Using regular chrome for one login and an incognito window for a second login appears to do the trick. However, opening multiple incognito windows does not allow you to login more than twice (it appears that all incognito tabs share the same process).
