# Log In

This node is used to log in users that exist in the Noodl Cloud Service. You need to provide a <span className="ndl-data">Username</span> and a <span className="ndl-data">Password</span> and then send a signal to the <span className="ndl-signal">Do</span> action.

<div className="ndl-image-with-background l">

</div>

Once a user is logged in, their data can be accessed through the <span className="ndl-data">User</span> node.
