Nowadays, any kind of application asks its users to verify their identity to access its services. Whether at work or to complete a certain task, for security reasons, <strong>the user needs to authenticate<\/strong> in one way or another. These systems allow organizations <strong>to guarantee the security of their networks<\/strong>, granting access only to those who are actually authorized to do so.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">In this article we tell you about the importance of the authentication methods, their different types and how you can use them with Viafirma.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">What are authentication methods?<\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Authentication methods are one or more <strong>IT procedures<\/strong> that make it possible to <strong>confirm that a user of a site or service is who he or she claims to be.<\/strong><\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">It provides<strong> access control to systems<\/strong>, checking whether a subject&#8217;s credentials match those registered in a database of authorized users or in a data authentication server. This ensures the<strong> security of the company&#8217;s systems, processes and information.<\/strong><\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Why are authentication methods important?<\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Access control is the basis of all security<\/strong>, since no unauthorized persons can be allowed to enter. This is done by confirming or authenticating the i<strong>dentity of the user<\/strong> requesting access and verifying that he\/she is indeed authorized to do so.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Before going through the different authentication methods, we must understand how important they are in our daily lives.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">We must visualize it as if it were our<strong> shield against any attack<\/strong>, allowing access only to those users who have been authorized to obtain this information.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">To strengthen this first line,<strong> companies are introducing new security measures<\/strong> in their processes, as <strong>cybercriminals can access a system and steal information when user authentication is not secure.<\/strong><\/p>\r\n\r\n\r\n\r\n<figure><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-35420 size-full aligncenter\" src=\"https:\/\/www.viafirma.com\/wp-content\/uploads\/2021\/12\/autenticacion-segura.webp\" alt=\"autenticaci\u00f3n segura\" width=\"1024\" height=\"640\" srcset=\"https:\/\/www.viafirma.com\/wp-content\/uploads\/2021\/12\/autenticacion-segura.webp 1024w, https:\/\/www.viafirma.com\/wp-content\/uploads\/2021\/12\/autenticacion-segura-300x188.webp 300w, https:\/\/www.viafirma.com\/wp-content\/uploads\/2021\/12\/autenticacion-segura-768x480.webp 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">5 popular authentication methods<\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Although there are many, here are some of the most important ones:<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">QR Authentication<\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">This model uses the device&#8217;s <strong>camera<\/strong> to scan the code and access the information or the platform.
