1, Every way for logging will create a new FarBox account automatically if there is no a existed account.

2, A existed Dropbox account that has no password to login to FarBox, can input the email address of your Dropbox account, then set the password.

3, If a non-Dropbox account wants to bind Dropbox: use your original way to login, then set `Account Info`, make the email address same to your Dropbox, and allow it to bind; then logout and re-login by Dropbox. But Dropbox is required indeed, FarBox has a desktop client, to handle cloud storage, sync and writing.
