The three types of factors are: something you know (password, PIN), something you have (token, authentication app, SMS code), and something you are (biometrics: fingerprint, facial recognition, iris). Combining factors from different categories makes unauthorized access extremely difficult, since an attacker would need to compromise factors of different types simultaneously.  <\/p>\n<p>[\/vc_toggle][vc_toggle title=&#8221;What is the difference between identification and authentication?&#8221; style=&#8221;arrow&#8221; color=&#8221;black&#8221; custom_font_container=&#8221;tag:h3|font_size:20px|text_align:left&#8221; custom_google_fonts=&#8221;font_family:Dosis%3A200%2C300%2Cregular%2C500%2C600%2C700%2C800|font_style:700%20bold%20regular%3A700%3Anormal&#8221; css=&#8221;&#8221; use_custom_heading=&#8221;true&#8221; custom_el_class=&#8221;mg-b-0 fondo-gris-preguntas-frecuentes&#8221;]<\/p>\n<p style=\"font-size: 16px;\">Identification involves declaring who you are: entering your username or email address. Authentication involves proving that you really are who you say you are: providing proof via a password, token, biometrics, etc. Identification is a claim; authentication is the verification of that claim. MFA strengthens authentication by adding additional layers that validate the declared identity and reduce the risk of impersonation.   <\/p>\n<p>[\/vc_toggle][vc_toggle title=&#8221;Does DORA require the financial sector to implement MFA?&#8221; style=&#8221;arrow&#8221; color=&#8221;black&#8221; custom_font_container=&#8221;tag:h3|font_size:20px|text_align:left&#8221; custom_google_fonts=&#8221;font_family:Dosis%3A200%2C300%2Cregular%2C500%2C600%2C700%2C800|font_style:700%20bold%20regular%3A700%3Anormal&#8221; css=&#8221;&#8221; use_custom_heading=&#8221;true&#8221; custom_el_class=&#8221;mg-b-0 fondo-gris-preguntas-frecuentes&#8221;]<\/p>\n<p style=\"font-size: 16px;\">Yes. The DORA Regulation (Digital Operational Resilience Act, EU 2022\/2554), in effect since January 2025, stipulates in Article 9 that financial institutions must implement robust access controls and strong authentication mechanisms as part of their ICT risk management. This applies to banks, insurance companies, investment funds, investment firms, crypto-asset service providers, and other entities in the European financial sector.  <\/p>\n<p>[\/vc_toggle][vc_toggle title=&#8221;What does NIS2 say about multi-factor authentication?&#8221; style=&#8221;arrow&#8221; color=&#8221;black&#8221; custom_font_container=&#8221;tag:h3|font_size:20px|text_align:left&#8221; custom_google_fonts=&#8221;font_family:Dosis%3A200%2C300%2Cregular%2C500%2C600%2C700%2C800|font_style:700%20bold%20regular%3A700%3Anormal&#8221; css=&#8221;&#8221; use_custom_heading=&#8221;true&#8221; custom_el_class=&#8221;mg-b-0 fondo-gris-preguntas-frecuentes&#8221;]<\/p>\n<p style=\"font-size: 16px;\">The NIS2 Directive (EU 2022\/2555) requires operators in essential and important sectors to adopt appropriate technical and organizational measures for cybersecurity risk management, including access controls and strong authentication mechanisms (Article 21).

MFA is the generic term that encompasses any combination of two or more factors. In practice, when regulations such as DORA, NIS2, or the ENS refer to \u201cstrong authentication\u201d or \u201crobust authentication,\u201d they are referring to MFA with at least two factors from different categories. The use of two factors from the same category (e.g., password + PIN) is not considered strong authentication.   <\/p>\n<p>[\/vc_toggle][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row type=&#8221;grid&#8221; css=&#8221;.vc_custom_1547557263471{margin-bottom: 0px !important;padding-bottom: 0px !important;}&#8221;][vc_column dp_animation=&#8221;&#8221; el_class=&#8221;El nuevo reglamento europeo obliga a recabar el consentimiento expl\u00edcito para el tratamiento de los datos de car\u00e1cter personal&#8221; font_color=&#8221;#81d742&#8243;][vc_single_image image=&#8221;43698&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row type=&#8221;grid&#8221; css=&#8221;.vc_custom_1679050935288{margin-top: 0px !important;padding-top: 0px !important;}&#8221;][vc_column dp_animation=&#8221;&#8221; css=&#8221;.vc_custom_1547557427896{padding-top: 0px !important;}&#8221;][vc_empty_space height=&#8221;80px&#8221; css=&#8221;.vc_custom_1742553516084{margin-top: -70px !important;}&#8221;][vc_column_text css=&#8221;.vc_custom_1787554397587{padding-top: 50px !important;padding-right: 50px !important;padding-bottom: 50px !important;padding-left: 50px !important;background-color: #F2F2F2 [&hellip;]<\/p>\n","protected":false},"author":18,"featured_media":43698,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[634,480],"class_list":["post-43687","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-certified-digital-identification","category-communication-solutions-with-legal-value"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Multifactor Authentication (MFA): What It Is and Why It Works<\/title>\n<meta name=\"description\" content=\"Securing access to corporate applications is a priority.
