In addition to a login and password, an additional code is required to be obtained. The code is one-time use and has a limited time of validity.<\/p>\n\n\n\n<p><strong>How does it work?<\/strong><\/p>\n\n\n\n<p>To use two-factor authentication, the user needs to install the Google Authenticator app for IOS or Android on their phone or computer. Thus, access to the personal account will only be possible from the owner&#8217;s trusted device. The six-digit confirmation code will be automatically generated in the app and has a limited time of validity of 30 seconds. Within this time, the account owner needs to enter the verification code to access their personal cabinet.<\/p>\n\n\n\n<p><strong>How to enable 2FA?<\/strong><\/p>\n\n\n\n<ol>\n<li>The two-factor authentication function must be activated in the Security section of the Personal Cabinet Settings.<\/li>\n\n\n\n<li>Install the Google Authenticator app on your IOS or Android phone or computer.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"637\" data-attachment-id=\"1739\" data-permalink=\"https:\/\/rx-name.net\/blog\/what-is-the-purpose-of-two-factor-authentication-2fa\/what-is-the-purpose-of-two-factor-authentication-2fa-screenshot-1\" data-orig-file=\"https:\/\/rx-name.net\/blog\/wp-content\/uploads\/2025\/09\/What-is-the-purpose-of-two-factor-authentication-2FA-Screenshot-1.png\" data-orig-size=\"1147,714\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"What-is-the-purpose-of-two-factor-authentication-2FA-Screenshot-1\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/rx-name.net\/blog\/wp-content\/uploads\/2025\/09\/What-is-the-purpose-of-two-factor-authentication-2FA-Screenshot-1-300x187.png\" data-large-file=\"https:\/\/rx-name.net\/blog\/wp-content\/uploads\/2025\/09\/What-is-the-purpose-of-two-factor-authentication-2FA-Screenshot-1-1024x637.png\" src=\"https:\/\/rx-name.net\/blog\/wp-content\/uploads\/2025\/09\/What-is-the-purpose-of-two-factor-authentication-2FA-Screenshot-1-1024x637.png\" alt=\"Set up two-factor authentication using Google Authenticator and QR codes.\" class=\"wp-image-1739\" srcset=\"https:\/\/rx-name.net\/blog\/wp-content\/uploads\/2025\/09\/What-is-the-purpose-of-two-factor-authentication-2FA-Screenshot-1-1024x637.png 1024w, https:\/\/rx-name.net\/blog\/wp-content\/uploads\/2025\/09\/What-is-the-purpose-of-two-factor-authentication-2FA-Screenshot-1-300x187.png 300w, https:\/\/rx-name.net\/blog\/wp-content\/uploads\/2025\/09\/What-is-the-purpose-of-two-factor-authentication-2FA-Screenshot-1-768x478.png 768w, https:\/\/rx-name.net\/blog\/wp-content\/uploads\/2025\/09\/What-is-the-purpose-of-two-factor-authentication-2FA-Screenshot-1-900x560.png 900w, https:\/\/rx-name.net\/blog\/wp-content\/uploads\/2025\/09\/What-is-the-purpose-of-two-factor-authentication-2FA-Screenshot-1.png 1147w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Step-by-step instructions for enabling two-factor authentication via Google Authenticator to increase account security<\/figcaption><\/figure>\n\n\n\n<p>3.
