Add-on Forcing Register and Login with Steam Integration

Hello there! I wanted to ask if anybody would be interested in making a thing that results in people being forced to login or register with Steam. I really want this added because it increases our security. If you wish to contact me further about it feel free to make a conversation using the via conversations tab. If you find interest for the job and once you made your conversation we'll talk about price, etc. Thank you!

What I want: I want an addon created so that it forces people to register and login with Steam. Disable the login with username and password.

NOTICE: If you find interest in this job make a forum conversation with @zombiekiller804 included in it. Thanks. After the Conversation is made more details will be discussed.
