Allow other options to Create an Account

Please provide other options for creating an account and not limit it to a Google or GitHub account. Limiting to just those two is pretty much the only reason I haven’t signed up yet. A few coworkers of mine also feel the same way; some have signed up using a junk account or a Google account specifically for sites that only offer Google registration. Need an option to just use an email that does not have to be associated with Google or GitHub, or any other service/site. Just a plain old email & password registration PLEASE

Thanks
