In my app I’m currently logging in users by redirecting the whole page to: `https://mycompany.eu.auth0.com/samlp/${appKey}?connection=myCompany` and then letting them fill in the form on the auth0 UI.

Can I use an auth0 API to log in using Javascript? Something like this?

```auto
import auth0Api from 'auth0/somewhereimaginary';
const username = usernameInput.value;
const password = passwordInput.value;
await auth0Api.login(username, password);

```

I’ve found this [Cross-Origin Authentication](https://auth0.com/docs/authenticate/login/cross-origin-authentication) which looks like it could be it but the page just has a load of text and then some irrelevant links at the bottom, but no JS code examples.

Hi @will.squire,

Welcome to the Auth0 Community!

You can exchange a username/password directly for a token using the [Resource Owner Password Flow](https://auth0.com/docs/get-started/authentication-and-authorization-flow/resource-owner-password-flow).

Let me know if you have any questions!
