Logins+security for a website


I am wondering if somebody can give me advice as to what login generator
should i be using for a website that I am building. It is somewhat of an
uncharted territory for me. I want to have some form of SSL
communication. I was looking into setting up cosign, but I think that it
would have been a bit too bloated of a setup. Any insights on any good
starter options would be great.
