General developer forum

i am running some websites on moodle. i am using Email-based authentication for them. what i found is many people are un-confirmed, may be they haven't got email from us or may be email went in there spam folder or whatever. the main point is i have lost many potential users.
as i m having many websites so it becomes difficult for users to register in all the websites.

i was searching for a solution when i found Google's account authentication api
http://code.google.com/apis/accounts/Authentication.html
and yahoo's account authentication api
http://developer.yahoo.com/auth/

they both can be used... in place of verifying users directly from there email we can use these codes/api's to verify user.

Advantages:-

1) it will be really fast and users wont have to wait for there verification
2) it will be more secure (as far as i think)

more can be added by experts (like you)

i have reported it in tracker
http://tracker.moodle.org/browse/CONTRIB-21

please vote and comment on it. also tell what u think, will it be that use full as i m thinking it may be?
