Describe the reasons for and methods of two-step verification processes. What information should a user use to register?

What will be an ideal response?

In an attempt to further protect personal data and information from online thieves, many organizations such as financial institutions or universities that store sensitive or confidential items use a two-step verification process. Withtwo-step verification, also known astwo-factor verification, a computer or mobile device uses two separate methods, one after the next, to verify the identity of a user.?ATMs (automated teller machines) usually require a two-step verification. Users first insert their ATM card into the ATM (Step 1) and then enter a PIN (Step 2) to access their bank account. Most debit cards and some credit cards use PINs. If someone steals these cards, the thief must enter the user's PIN to access the account.?Another use of two-step verification requires a mobile device and a computer. When users sign in to an account on a computer, they enter a user name and a password (Step 1). Next, they are prompted to enter another authentication code (Step 2), which is sent as a text or voice message or via an app on a mobile device (Figure 5-12). This second code generally is valid for a set time, sometimes only for a few minutes. If users do not sign in during this time limit, they must repeat the process and request another verification code. Microsoft and Google commonly use two-step verification when you sign in to their websites. If you sign in from a device you use frequently, you can elect to bypass this step.?Users should register a landline phone number, alternate email address, or other form of contact beyond a mobile phone number so that they still can access their accounts even if they lose their mobile phone.
