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 https://alpaca.markets/docs/build-apps_services-with-alpaca/oauth-guide/

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?
