What is 2FA and why should I need it?
Two-factor authentication (2FA) requires users to provide two different types of information, e.g. a password and a secondary verification (such as an approval from your smart phone), before accessing their accounts. This helps to prevent unauthorized access even if your password is stolen.
Please refer to Duo 2FA website for more information.
Solution
The enrollment could be done using a smartphone solely or using a smartphone and a computer. The steps using either method is identical.
