...whenever you go to Hotmail...you can choose to get a single-use code–a string of numbers that will be sent via text message to your phone–to use instead of your password.
- Is this an accurate description of Hotmail's system?
- If so, does Hotmail really offer two-factor authentication? If you can use either your password or a single-use code, it seems to me that it does not.
- Is this system really more secure than just having a password? Doesn't this just make an additional "key" available to a hacker? (I must be wrong here, I know the folks at Microsoft are much smarter than I am).
