If you didn’t change your password after your first deployment, you can still see it by pressing the Get Access button on your ubiDesktop dashboard.
If the password that used to work doesn’t work anymore and you are sure you didn’t change it, then it is likely that your virtual desktop has been hacked.
Unfortunately, if you changed your password and you forgot it, we can give very little help. You should use VNC and follow the recovery procedure of the Operating System, if available.
In case you don’t have any important data on your virtual desktop, you can reinstall the system from scratch by pressing the Reinstall button (this will erase all data).
