The reason behind a separate input sequence is because Springnote uses OpenID. Your OpenID has to be authorized by your OpenID provider's web site.
When you sign on to a web service, you send an ID to the service and a password to your OpenID provider. This is the reason why you have to enter an ID first and then password later. The first merit of a connection between an OpenID provider and an OpenID–enabled web service is that it is very secure. You do not have to let web services know your password.
For your security, when you enter your password, you will have to check the URL on your browser to verify whether your OpenID site address is correct or not. If the web-site address is not correct you must not enter your password.

OpenID lets you use only one ID to access thousands of websites. As one of the ID-providing services, myID.net is based on an ID authentication technology. Springnote uses myID as a default service when users sign up.
You can use Springnote's OpenID to access other websites that support OpenID.
Any OpenID is accessible at Springnote.
OpenID eliminates the need for multiple user names across various web sites simplifying your online experience.
