Diigo team takes pride in our attention to detail to constantly innovate and improve your user experience. To make the sign-in / create new account process even easier for our users, we’ve just implemented additional support for Facebook, Twitter, Google Yahoo, other OpenID account ID. So now you can log into Diigo using any of your existing account credential:
Once you sign in with other account credential,
1) if you already have an existing diigo account, we can associate those 2 accounts together, OR
2) if you don’t have a diigo account yet, we can auto-create a new diigo account for you:
After associating your other credential with your Diigo account, you will be able to login with your Facebook/Twitter/Googl ID/Yahoo ID.
Btw, another frequently requested feature: “can I change my username?” Yes, now you can! Login first then visit https://secure.diigo.com/setting to change your diigo username and/or password (note: min 6-character username restriction still applies.)
