# Log In
This component is used to log a user in. Once email address and password are set, the sign up is triggered after a signal is sent to the `Do` input.
<div className="ndl-image-with-background xl">
![](/library/prefabs/supabase/login.png)
</div>
> Please note that [Supabase Client](/library/prefabs/supabase/components/setup-client/) needs to be set up in your app before you can properly use this component.
## On success
When a user has successfully been logged in the **Log In** component will create a Noodl Object with the id `currentUser`. This object contains all the user data. You can use the **[Supabase - Fetch Current User Profile Data](/library/prefabs/supabase/components/supabase-update-current-user-profile-data)** to refresh all non-auth data for the user.
A successful login will also trigger a `Supabase User Logged In` event. You can hook into to this event anywhere in your app using a [Receive Event](/nodes/events/receive-event/) node.
