How To Set Up Google 2-Step Verification?

In An Era When Information Security Is One Of The Biggest Issues, And Everyone Is Concerned With Online Safety, There Is An Ever Growing Demand For Stronger Website And Application Security. One On The Best Ways To Do So Is To Use A Two Factor Authentication. Today, Three Factors Are Available For Authentication:


·         Information Known To The User, Such As A Password Or A Question They Alone Can Answer.

·         Physical Property, Such As A Mobile Device Or A Token Chip.

·         Something No One Else Can Possess, Such As A Fingerprint.


The Preferred Method Of Upgrading Your Security Is To Use Two Of These Factors.


With Technology Developing In Such Ways That Would Enable To Use Retina And Fingerprint Scans More Efficiently In The Very Near Future, Most Devices And Software Still Do Not Offer Such An Option, Thus Rendering This Option To Be Less Available And Less Effective. Most Of The Software, And Hardware, Available At This Time Offer An Option To Install An App On Your Phone That Would Enable To Send A One-time Numeric, Or Alpha-numeric, Code Directly To Your Phone From Anywhere On The Net, Without Having To Input Your Phone Number – This Is The Preferred Go-to Option Most Users Would Choose.


Current Authentication Software That Enable This Option Are Such As Google Authenticator, Twilio Authy And Dou Mobile. All Are Available For Free On IOS™, Android™and BlackBerry™phones, With Free Access Versions That Provide All The Features Required, Some Of Those Are Even Available On Chrome™browser. Codes Provided By Those Software Option Sync Directly With Your Phone And Also Across Your Accounts So You Can, Later, Scan A QR Codewith Your Phone To Gain Access Via A Generated Code On Your Browser.

Google Calls Its 2FA System 2-Step Verification, And It Utilizes Your Smart Phone To Enable A 2 Factor Authentication System.


The First Option Is To Simply Add Your Smartphone To Your Account, And Upon Login Just Use Your Phone To Acknowledge That You Are The One Signing In. Simply Make Sure That The Google Search App Is Installed On Your Smartphone, And That's It! Simple!

This Is Called Google Prompt, And It Now Exists For Every Smart Phone With The Google Search App Installed On It. It Uses A Simple Yes/No Mechanism, Where You Simply Press "Yes, Authorize Access" Or "No, I Did Not Sign In".


Another Option Is To Use A Numeric. Or Alpha-numeric, Code Sent To Your Phone Via SMS, Voice Message Or Via Any Authenticator App (the Ones Mentioned Above, For Example). With This Option You Can Opt To Register Your Personal Computer So That You Do Not Have To Enter A New Code Every Time You Login, This Option Will Enable You To Use A Once-per-month Authentication Code.


Here Is A Link To A You-Tube Video With An Explanation On How To Setup Your Google 2-Setp Verification:


Authenticator Apps Can Generate A Verification Code Even If Your Phone Is Not Connected To The Internet, To Do So You Must First Sign-up For The 2-Step Verification Beforehand. After Signing Up You Can Use The App To Scan A QR Code On The Desktop Screen, And Then The App Will Generate A Time-based, Or Counter Based, Code For You To Type In As The Second Factor. Authenticator Apps Will Sync With Other Services, Such As: LastPass, WordPress, Facebook, Evernote Or Dropbox.


Once You've Set Up Google 2-Step Verification You Can Then Access Your Google Account Security Settings And Add Or Change The Phone Number/s Used To Receive The Codes, Or Switch To The Authenticator App Of Your Choice. In Case You Do Not Have Access Via Your Phone (i.e. When The Battery Is Dead) You Have Your 10 Unused Codes To Use In Emergencies, You Can Access Them As Well Via Your Account Security Settings And Print Them Out.


What Other Ways Of Using 2 Factor Authentication Are There?


Yes, There Are.

One Of Those Ways Is Using A Mechanism Known As OTP, Or One Time Password. The Idea Is To Generate A Random, Numeric Or Alpha-numeric, Code, That Is Made To Be Affective One Time Only, And Sending This Code To Either A Mobile Device Or Via E-Mail.


There Are Many Services That Provide Various API Methods To Execute OTP, Among Them Are Cellular Providers (Such As Nexmo) Or Other Service Providers Dedicated To Messaging Services (Such As Telesign) Or Even E-Mail Service Providers (such As Mailchimp).


Basically, OTP Mechanism That Enables The User To Receive A Code Valid For A Single Transaction Or Login. It Executes The 2FA Perfectly By Referring The User, Which Had Already Provided The Information Required For The First Authentication Factor, To Use A Device, Or An E-Mail Account, To Provide The Second Factor.


Most OTP's Are Time-limited, And Rely On Fast Delivery Of The Code Generated By The Software, Or Website, To The Client (either The User's Mobile Phone, Other Mobile Device, Or E-Mail Address). By Doing So They Reduce The Chances Of The OTP To Be Discovered By An Outside, Third Party, Source. However, Some OTP's Do Not Rely On Fast Delivery, And Are Actually Utilizing Manual Delivery (i.e. Physical Mail), Those Are Often Considered Old-fashioned On One Hand, Yet Extremely Secure On The Other.
