New authentication schemes such as OpenID, or Microsoft's CardSpace, may help as adoption increases. These systems make it possible to register for one site using credentials verified by another. Instead of having many sites with poor verification procedures, the internet could have a few sites with strong verification procedures, that are then used by others. The advantage for the user is that they no longer have to jump through multiple hoops for each new site they encounter.
