Oh, sorry for the misunderstand. I mostly meant this for e-commerce and for a SaaS' informal trial part only, not the part where you actually need to create an account. In e-commerce cases, you're usually just fine with an address (since you need to ship), an email or phone or some kind of order tracking ID. In most SaaS cases you can ask for nothing - literally - as visitors try out your product. Allow them right in, and sprinkle a few "sign up" links or forms where appropriate. Build trust, basically. More often than not, you can delay creating an account proper until you're beginning the formal trial period or processing the credit card.
