What is 
?
It's a single username and password that allows you to log in to any OpenID-enabled site.
Thousands of websites already support it, because who wants to remember another password? OpenID uses ONE across all kinds of different sites, without actually giving that password to each site! The official OpenID website has all the details.
Where do I get an OpenID?
You may already have one! Lots of big websites are OpenID "providers". If you have an account with them, you're ready to go!
We already offer 1-click support for Google, Yahoo, AOL, LiveJournal, Flickr, Wordpress, Blogger, Verisign, and more!
Want more choices? Get your own OpenID.
How can I use it with BioGPS?
You can use your OpenID to create a new account or link it with your existing BioGPS account. Either way, you will then be able to sign in using your OpenID provider and you won't have to use or remember a separate password for BioGPS.
