What Is Multi-Factor Authentication

What Is Multi-Factor Authentication (MFA), And How Is It Different from 2FA? – By Anthony Heddings cloudsavvyit.com

Two Factor Authentication, or 2FA, has been around for a while. It usually refers to using an SMS code as an additional step for logging in to your account. However, the term has been being replaced by “Multi-Factor Authentication.” What’s the difference?


The YubiKey 5C NFC Can Unlock Your Phone, Tablet, Laptop, or Desktop – By Josh Hendrickson reviewgeek.com

Whether you’re on the go or working from home, locking your electronics is always a tricky balance of security and convenience. A device can either be totally secure or incredibly convenient to access, but not both. Yubico’s latest security key, the $55 YubiKey 5C NFC, might have the balance just right.

The Beginner's Guide to PC Backup – By Eric Griffith au.pcmag.com

We all know we're supposed to back up our data. It's essential to a person's well-being and peace of mind, and one copy of a file on your computer does not a backup make. Redundancy, people, redundancy!

How to use copy and paste on a Chromebook – By Andrew Myrick androidcentral.com

It should come as no surprise that as time has passed everyone by, Chromebooks have progressed and become true productivity machines. And while these devices give us a lot of functionality that you won't find elsewhere, you'll likely want to know how to do some of the more basic tasks. One such task that is performed a plethora of times per day is to simply copy and paste text or other items from one place to another. Here's how you can do so right from your Chromebook.

Why People Look Different in Photos Taken with Different Lenses – By Harry Guinness howtogeek.com

If you’ve ever taken a close-up portrait of someone with your smartphone’s wide-angle lens, you might have noticed they look a little . . . off. Maybe their nose seemed a bit big, or their face was just a tad too wide. You weren’t imagining it.

Two-factor/Multi-factor authentication">> Two-factor/Multi-factor authentication

Multi-factor authentication and Two-factor authentication (2FA) Resources

I agree with experts, who suggest using Two-factor authentication on all of your accounts that offer it. Most banks and credit unions require 2FA. It's the code they send to you by SMS text, email, or a voice call. 

  • I have included articled from five sourced describing what 2FA is how to use it and many web sites that offer it as an option to secure your account.
  • After learning what 2FA is, you will find a great article by PCmag, "Who Has It and How to Set It Up." It's a great guide to implementing 2FA is sites most of us use.
  • Perhaps as impotent as implementing 2FA is avoiding getting locked out of your accounts when using Two-Factor Authentication.
  • I use Authy in place of Google Authenticator. Authy synchronizes to the cloud allowing use on multiple devices, including phones, tablets, computers, and browsers, making it both convenient to use and eliminates the issue moving to a new phone or computer.

Multi-factor authentication and Two-factor authentication – By From Wikipedia, the freeen.wikipedia.org

Multi-factor authentication is an authentication method in which a computer user is granted access only after successfully presenting two or more pieces of evidence.


Two-factor authentication – By Chris Woodford explainthatstuff.com

How careful are you when it comes to securing your computer? Do you take pains to choose complex passwords and not write them down where other people can find them? Even if you do, isn't it just possible someone else could hack into the systems you use and do all kinds of damage?


Two-factor authentication (2FA) – By Margaret Rouse searchsecurity.techtarget.com

Two-factor authentication (2FA), sometimes referred to as two-step verification or dual-factor authentication.


How Does Two-Factor Authentication (2FA) Work? – By Brad merchantfraudjournal.com

Two-factor authentication is the best way to protect sensitive data from theft.


How does multi-factor authentication work (technically)?  – Christian Roberts, Security Engineer at Protectimus Solutions

The most popular second factor is OTP (one-time-password). Usually, it is 6 or 8 digits password, which could be delivered to users via SMS or email or generated by software or hardware token.




Two-Factor Authentication: Who Has It and How to Set It Up – By Eric Griffith pcmag.com

You can get that code via text message or a specialized smartphone app called an "authenticator." Once linked to your accounts, the app displays a constantly rotating set of codes you can use whenever needed—and it doesn't even require an internet connection. The arguable leader in this area is Google Authenticator (free on Android and iOS). Twilio AuthyDuo MobileSAASPASS, and LastPass Authenticator, among others, all do the same thing on mobile and some desktop platforms, and the majority of popular password managers all have 2FA by default.

The codes provided by authenticator apps sync across your accounts, so you can scan a QR code on the phone and get your six-digit access code on your browser if supported.

SecurityWatch: How to Not Get Locked Out With Two-Factor Authentication – By Max Eddy pcmag.com

What happens if I lose my password? Or if my antivirus deletes my stuff? The advent of two-factor authentication has created a new twist on familiar anxiety: what happens if I can't use my second factor and get locked out of my account?


How to Avoid Getting Locked Out When Using Two-Factor Authentication – By Chris Hoffman howtogeek.com

What happens if you lose or reset your phone? If you don't plan your recovery method ahead of time, you could permanently lose access to your accounts.





2FA questions

  • Who initiates the process to set up the authenticator app, by which I mean, who generates the code for a transaction?
  • Is it always the merchant, or does the customer sometimes initiate it? i.e., Are there some merchants who let the customer initiate the app to generate a six-digit code?

The confusion comes because of Authy. As I understand Authy, that the program generates a six-digit code. 

  A: Authy app requires a cell phone number to set up. I also have Mac, Win10, and Chromebook apps. gmm 

  • Banks don't require the use of the cellphone when a log-on attempt comes from my desktop computer.

  A: SMS to a cell phone is much faster and works when not at your home.

  • To continue my question, how is it that Authy can generate a six-digit code that is useful if the merchant always and only creates a code that it will accept and recognize? I have not gotten Authy to work yet?

A: Authy and Google Authenticator use TOTP (Time-Based One-Time Password) algorithm that generates short-lived OTPs to provide additional security to users' accounts. Generated passwords are temporary and valid a certain amount of time (usually 30-60 seconds). TOTP algorithm based on HOTP with a time-based moving factor described in RFC 6238.

OTP (one time password) is sent to an Authentication server by a user, for authentication validation is synced based on time.

There are three factors involved in the OTP generation process:

  1. Time(T1)
  2. Serial no. of a token (secret key)
  3. Algorithm(A1)
  • Are there merchants who let the customer generate the 2fa six-digit code for a transaction? 

A: OTPs are generated based on the secret key. Usually, the server generates the secret key, and the token programs the secret key into the app, allowing the generation of OTPs by the app. The server checks OTP, and if it's correct, the server provides access to the system.

Turn on MFA Before Crooks Do It For You By krebsonsecurity.com 

Many popular websites now offer some form of multi-factor authentication (MFA), which helps users safeguard access to accounts if their password gets breached, stolen, or guessed. But people who don’t take advantage of these added safeguards may find it far more difficult to regain access when their account gets hacked. Increasingly thieves will enable multi-factor options and tie your account to a device they control. Here the story of one such incident. Turn on MFA Before Crooks Do It For You
