ResScan 6.0 was upgraded to run on a Local Area Network with multiple user access. Anyone with network access can login to the network with any computer on the LAN and then launch ResScan using the same user name and password for the LAN. For a stand alone PC, this complicates things a bit.
I figured out how to login to ResScan 6.0 on my windows 10 computer.
1. Go to Settings/Accounts and it will display whether you are using a local account or Microsoft Account.
2. If you are using a Microsoft Account, it will display your user name as your email. I use a passcode to sign into my computer. ResScan 6.0 will not accept your email address for user name and passcode for password. (I use Microsoft Account so my Office 365 apps can sync across multiple devices (smartphone, tablet, other PC). I had to switch to LOCAL ACCOUNT to be able to login to ResScan 6.0. By switching to local account, it disconnected me from Microsoft Account.
3. Go to Settings/Accounts/Sign in Options and add a password if you don't have one. If you have multiple user accounts, you only need to add password to the account you want to run ResScan. When you create your password, be sure you put in a HINT so you can recover it if you forget it. There is no way to recover Windows 10 password so be sure your HINT is one that will help you remember. The only option you have if you cannot recover the password is do a fresh install of Windows 10. You can also add a passcode so in the future, you only need to remember a 4-digit code to login to your computer.
4. Now you can launch ResScan 6.0 and use your local account user name and the password you created or previously created when you installed Windows 10. (don't use the passcode)
When I am done using ResScanI have to switch back to Microsoft Account to continue syncing my Office 365 apps with other devices. This is real pain in the a**. So every time I want to use ResScan, I have to switch to local account (logs me out of Microsoft Account). Then switch back to Microsoft Account when I am done with ResScan.
I will be using SleepyHead, but when I want graphs and data I want to show my doctor, I need to create them in ResScan so doctor will know it is valid data.
I did notice that SleepyHead and ResScan data are not exactly the same. But close enough to monitor your sleep without having to jump hoops to use ResScan.
