How to make a successful sign in and login with a username?

Hi! So I’m working on an app for my class, and it’s meant to be a social media type thing, so I need a log in that let’s you actually log in lol. I’ve been trying for 2 class periods now and I still can’t get how you might go about creating one??? The sign in I have doesn’t let you sign up or log in at all, so I just need a simple log in with a username please!!!

thank you,

@oOF, Have you seen our documentation for the Sign In component here? If so, can you provide some more details about the behavior that your seeing?
