I hear uoZone has a single-sign-on process. What is that?

Single-sign-on allows you to access multiple Web applications and tools using one and only one password authentication. uoZone has this capability. However, the first time you log in to your e-mail via uoZone, you need to provide an initial, once-only password authentication. uoZone then saves the login information for your next session. For all other Web applications, uoZone does not require an initial password authentication.
