We allow signing in using several third party account providers such as Google, Yahoo, Facebook, etc. The benefit of this approach is that you don't need to remember yet another password but use your existing accounts in these providers.
Even if you've registered with a local account, you may always link it to an external login provider by using the [Manage Account] link.
Similarly, if you have registered using an external provider, you may always set a local password as well
To register with a third party provider all you have to do is clicking on the icon of the provider in the registration page and enter your user id and password. This will have the benefit of logging into the ICD-11 Browser either with your local account or with any of the third party providers option that you have linked
Once your registration is complete, logging into ICD-11 Browser using the external provider is simply done by clicking the provider's icon in the Log in page.
