User Registration with Email Verification

I want to verify user registration by sending email.

The email consist the Username and Password which he/she used at registration time and a Link on which user can click and account verified if he/she exists in database.
I followed some tutorials but could not achieve success.

Give me some suggestions.

Thanks.
