Can we login with username and password instead of API

The documentation suggests Alpaca will only allow us to use its API with a user’s Key Id and Secret Key. Is there a way to use the API with just a username and password? In other words, if there is an app that enables users to create Alpaca accounts to trade, can they get a login, or can there be some sort of workaround so these non-algo users do not have to enter API credentials?

look in to oauth

If it’s in the documentation, it’s not clear to me either, how you authenticate using the username and password.

Can someone explain whether its possible to login with username and password with OAuth?
