As you can see from the last few posts, I’ve been busy today with the w8track application. I managed to pull together a bunch of things I’ve been working on over the past several days. The most pervasive change was breaking apart the identity model. Previously, there was a one-to-one relationship between an OpenID identifier and an account. Now, multiple identities can share the same account. If you’re a user logging into w8track for the first time with a new OpenID, you’ll now be given the option of creating a new account or of associating the identity with an existing account using the secret account key I described in an earlier post. If, like me, you have several OpenIDs, you can associate all of them with one account, so you won’t have to remember later which one you used when you log in each morning to track your weight.
