Hello,
Your Hotmail account will serve as your Microsoft account when you add it to your Windows 10. This will give you access to apps and game from the Windows Store and let's you see your settings and other stuff across multiple Windows 10 devices.
To get started, you need to go to Settings > Accounts
> Email & app accounts. Under Accounts use by other apps, select
Add a Microsoft account. Follow the prompts to add your Microsoft account and you also need to verify your identity by entering a confirmation code.
Since you're also having issues with Windows Hello, we'd like to clarify the following information for us to properly isolate the concern and provide a more established resolution:
- Does Windows Hello facial recognition ever worked before?
- What is the make and model of your device?
We're looking forward to your response.
