WHAT’S THE BEST WAY TO SIGN IN?
When you sign up for an app or web account, it’s easy to log-in using tools provided by Facebook or Google with a single click.
You are better off creating your own username and password unique to that site.
Less of a chance, to gather or monitor what you are ordering on-line.
Create a strong password, not a recycled password such as password123!
