Which App Engine Authentication Method should I choose? (Pros/Cons)

Question

I am experimenting with Google App Engine and as I went to create an app it asked me to choose an authentication method. Options are 'Google Account' or 'OpenID', the 'Google Apps Domain' option doesn't interest me. However, I can't find very much information in the documentation that lists pros/cons of either method.

My question is what are the pros and cons of each of the methods?

Thanks.

Answer 1

Not sure of the exact pros and cons but the biggest is with

• Google Account - the users are forced to have a Google Account
• Open ID - the users must have an account with an Open ID provider which currently are listed here.

Open ID is how logins on StackOverflow works.
