When OpenID was made public, it seemed like a really good idea, solving the problem of having to maintain dozens or hundreds of user accounts all over the web.

But Stefan Brands has another point of view and he not only points out one or two flaws of the new identification and authentication protocol, but a whole list at a time:

• Security problems
• Privacy problems
• Trust problems
• Usability problems
• Adoption problems
• Availability problems
• Patent problems

After reading his article "The problem(s) with OpenID", I guess I'll go back to using Keepass.
