While going online has several advantages, cyberattacks have also increased. In fact, <a href=\"https:\/\/www.prnewswire.com\/news-releases\/top-cyber-security-experts-report-4-000-cyber-attacks-a-day-since-covid-19-pandemic-301110157.html\" target=\"_blank\" rel=\"noreferrer noopener\">4,000 cyberattacks are reported a day<\/a> since the pandemic.<\/p>\n<p>If you\u2019re not careful, your online accounts can get tampered with and violated. With that, setting a strong password is more important than ever. But bear in mind that even the strongest passwords just aren&#8217;t enough anymore.<\/p>\n<p>A good way to provide an extra level of security online is to employ two-factor authentication (also known as 2FA and multi-factor authentication).<\/p>\n<h3>What is Two-factor Authentication?<\/h3>\n<p><span class=\"TextRun SCXW258689096 BCX0\" lang=\"EN-US\" xml:lang=\"EN-US\" data-contrast=\"auto\"><span class=\"NormalTextRun SCXW258689096 BCX0\">Two-factor authentication is an added layer of protection when accessing your account. Besides providing your username and password, you will be asked to give another <\/span><span class=\"NormalTextRun ContextualSpellingAndGrammarErrorV2Themed SCXW258689096 BCX0\">crucial information piece<\/span><span class=\"NormalTextRun SCXW258689096 BCX0\"> that only you know. It could be one of the following:<\/span><\/span><span class=\"EOP SCXW258689096 BCX0\" data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:1,&quot;335551620&quot;:1,&quot;335559685&quot;:0,&quot;335559737&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<ul>\n<li>Something you know (i.e. a personal identification number (PIN), a password, an answer to a secret question, or a keystroke pattern)<\/li>\n<li>Something you have (i.e. a credit card, a one-time passcode (OTP), a smartphone, or a small hardware token)<\/li>\n<li>Something you are (i.e. a biometric pattern of a fingerprint, an iris scan, or a voice print)<\/li>\n<\/ul>\n<h3>How Does It Work?<\/h3>\n<p>The good thing about two-factor authentication is that it\u2019s customisable depending on the nature of your business. To give you an idea of what you can work with, you can learn from these companies:<\/p>\n<h4>Google<\/h4>\n<p>The search engine\u2019s two-factor authentication activates whenever a user signs up on an unfamiliar device. Google has several <a href=\"https:\/\/www.google.com\/landing\/2step\/#tab=how-it-works\" target=\"_blank\" rel=\"noreferrer noopener\">authentication methods<\/a>.<\/p>\n<p>Users could either choose to receive their authentication code through <a href=\"https:\/\/www.google.com\/landing\/2step\/features.html\" target=\"_blank\" rel=\"noreferrer noopener\">text or phone call<\/a>. The company also developed an Authenticator App where users can verify their web activities while offline. If you receive a notification through email regarding unfamiliar online activity, you can decide what to do next. The ideal step would be to change your password.<\/p>\n<h4>Paypal<\/h4>\n<p>Similar to Google, Paypal also notifies users of suspicious activity and requests confirmation by sending an SMS verification code. If the user fails to authenticate, then the site immediately sets the account on <a href=\"https:\/\/www.turnon2fa.com\/tutorials\/how-to-turn-on-2fa-for-paypal\/\" target=\"_blank\" rel=\"noreferrer noopener\">security hold<\/a>. This method was intended so that it prevents funds from being maxed out mistakenly.<\/p>\n<p style=\"text-align: center;\"><strong>Read: <a href=\"https:\/\/www.crazydomains.my\/learn\/enhance-website-security\/\" target=\"_blank\" rel=\"noreferrer noopener\">10 Steps to Enhance Your Website Security<\/a><\/strong><\/p>\n<h3>Why Is Two-Factor Authentication Important?<\/h3>\n<p>While important, usernames and passwords on their own can be easy to hack.

There are several forms of two-factor authentication used today; some are stronger or more complex than others, but they all provide better security than simply using a password.<\/p>\n<p>Here are the most common forms of 2FA:<\/p>\n<h4>SMS authentication<\/h4>\n<p><img decoding=\"async\" class=\"alignnone wp-image-38359 size-full\" src=\"https:\/\/www.crazydomains.com\/learn\/wp-content\/uploads\/2016\/12\/SMS-authentication.jpg\" alt=\"SMS authentication\" width=\"728\" height=\"245\" srcset=\"https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/SMS-authentication.jpg 728w, https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/SMS-authentication-300x101.jpg 300w, https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/SMS-authentication-400x135.jpg 400w\" sizes=\"(max-width: 728px) 100vw, 728px\" \/><\/p>\n<p>SMS authentication\u2014also known as SMS-based two-factor authentication (2FA) and SMS one-time password (OTP)\u2014is one of the most common and simple forms of authentication.<\/p>\n<p>After a user signs in to an app or website, they will receive a text message with a one-time code. The user then enters the code on the app or website to gain access.<\/p>\n<h4>Authentication app<\/h4>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-38360\" src=\"https:\/\/www.crazydomains.com\/learn\/wp-content\/uploads\/2016\/12\/Authentication-app.jpg\" alt=\"Authentication app\" width=\"728\" height=\"245\" srcset=\"https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/Authentication-app.jpg 728w, https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/Authentication-app-300x101.jpg 300w, https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/Authentication-app-400x135.jpg 400w\" sizes=\"(max-width: 728px) 100vw, 728px\" \/><\/p>\n<p>The authentication app method uses a time-based one-time passcode, also called TOTP. It uses apps such as Google Authenticator, 1Password, Authy, LastPass, OTP Manager, and Microsoft Authenticator.<\/p>\n<p>Once a user signs in, they will go to the authentication app to generate a time-sensitive code. Similar to SMS 2FA, the user has to enter the generated code along with their username and password in order to sign in.<\/p>\n<h4>Biometric authentication<\/h4>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-38361\" src=\"https:\/\/www.crazydomains.com\/learn\/wp-content\/uploads\/2016\/12\/Biometric-authentication.jpg\" alt=\"Biometric authentication\" width=\"728\" height=\"245\" srcset=\"https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/Biometric-authentication.jpg 728w, https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/Biometric-authentication-300x101.jpg 300w, https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/Biometric-authentication-400x135.jpg 400w\" sizes=\"(max-width: 728px) 100vw, 728px\" \/><\/p>\n<p>Biometric authentication is a security method that involves a person\u2019s biological characteristics. This includes retinal or iris scans, fingerprint login, face and voice recognition.<\/p>\n<p>This form of authentication works by comparing a user\u2019s biometrics to the information stored in a database. For example, a user places their finger on a fingerprint scanner. The system analyzes the image and then compares it against the stored sample. If their fingerprint matches the stored sample, the user is permitted access to the website.<\/p>\n<h4>Hardware token<\/h4>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-38362\" src=\"https:\/\/www.crazydomains.com\/learn\/wp-content\/uploads\/2016\/12\/Hardware-token.jpg\" alt=\"Hardware token\" width=\"728\" height=\"245\" srcset=\"https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/Hardware-token.jpg 728w, https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/Hardware-token-300x101.jpg 300w, https:\/\/www.crazydomains.com.au\/learn\/wp-content\/uploads\/2016\/12\/Hardware-token-400x135.jpg 400w\" sizes=\"(max-width: 728px) 100vw, 728px\" \/><\/p>\n<p>A hardware token is a small hardware device, often in the form of a key fob that can be stored on a key ring.
