Mobile Users and Accounts

The initial account that you used during setup is called the primary account. This account is used to create a user profile for you on the device. ​The user profile is sort of like your user account in a mobile device.

 ​In iOS and Android the primary account can be used to synchronize settings and ​data to the cloud. ​When you replace the device or set up a new mobile device with a primary account ​that you’ve used before you’ll have the option to restore data and ​apps if any have been backed up to the cloud

.Also in iOS and Android, a user profile can be signed into additional accounts. These could be additional email accounts, social media accounts or something else. ​If given permission apps on the mobile device can use these accounts for ​single sign on or SSO. ​This means that instead of those apps asking you for another user name and ​password they will allow you to authenticate using an account that you’re ​already signed into.

• Single sign on (SSO): An account that grants you access to multiple accounts without require constant entry of a password or username

Biometric data: A way of protecting your accounts and information using biometric data such as facial recognition and fingerprint
