Windows 8 will include an optional sign-in using Windows Live which will sync user settings, customization options, Metro-style apps, store passwords to other websites and files stored online using Windows Live, according to the latest Building Windows 8 post.
Users don’t necessarily have to sign-up to the Windows Live service to create a new account as the service is able to use your own email provider address as the username to sign-in. Katie Frigon, Microsoft Program Manager for the “You-Centered Experience team”, said “the firstname.lastname@example.org address is just a convenient way of identifying you, since most Internet users these days have email addresses”.
By allowing the Metro-style apps to be kept in sync, users will only have to buy an app once to use it across their devices such as tablets or desktop computers and when using public computers. Frigon saying “you can pick up on the same page of a book, the same level of a game, or the same place in the movie you were watching as you switch between your Windows 8 PCs.”
All services which connect to the Windows Live ID, which Microsoft say will include apps and websites, will not require further authentication. However, the automatically authenticated apps will not get further access to personal data unless allowed.
Passwords can be reset using the Windows Live account and when accounts are compromised, accounts will have features limited. “First, we do not roam data over WWAN by default. Second, all user data is encrypted on the client before it is sent to the cloud” said Frigon, in relation to securing data.
Statistics released on Building Windows 8 showed that shared PC usage occurs in 72% of desktops and 49% of laptop. They also found that 25% of people shared one account and 35% had one account for each user.
