Finally I've gained access into my Zimbra Desktop through a Browser. That is really, really useful and avoid to synchronize information between different computers... Just one account in running in my local hard disk accessible through any browser.

However the access is allowed through a key:

My question is: Is it possible to add a username and password to allow access into ZD?

Thank you!
