Authentication Services

Question

I have a web application (based on Java and GWT) that requires an authentication mechanism (login, logout, password reset, etc.).

I don’t want to spend time on its implementation, so I’m looking for services that allow the user to enter my web application using his existing accounts, such as Twitter, Facebook, etc.

I found one such service called loginza.ru.

Are there any alternatives?

Thanks in advance

Dmitry
