Using a dedicated app ensures that the scan is performed by a trusted device and that the data is handled within a secure, encrypted environment rather than through a generic consumer camera app. Protect your business from credential-based attacks by modernizing your authentication flow.

QR codes are dynamic and expire quickly, which prevents the most common attacks like credential stuffing and keylogging. When paired with biometrics on a trusted mobile device, they provide a much higher level of assurance than a static password that can be phished or reused across multiple sites.","inLanguage":"vi"},"inLanguage":"vi"},{"@type":"Question","@id":"https:\/\/pageloot.com\/blog\/qr-codes-vs-passwords-in-sso\/#faq-question-0ca394ada61e","position":2,"url":"https:\/\/pageloot.com\/blog\/qr-codes-vs-passwords-in-sso\/#faq-question-0ca394ada61e","name":"M\u00e3 QR c\u00f3 th\u1ec3 thay th\u1ebf ho\u00e0n to\u00e0n SSO kh\u00f4ng?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"QR codes do not replace SSO; they serve as a more secure delivery mechanism for it. They work alongside existing protocols like SAML and OpenID Connect to pass credentials between a device and a server. Instead of typing a password to trigger the SSO flow, you scan a code to achieve the same result more quickly and securely.","inLanguage":"vi"},"inLanguage":"vi"},{"@type":"Question","@id":"https:\/\/pageloot.com\/blog\/qr-codes-vs-passwords-in-sso\/#faq-question-9db47b02be5b","position":3,"url":"https:\/\/pageloot.com\/blog\/qr-codes-vs-passwords-in-sso\/#faq-question-9db47b02be5b","name":"Ng\u01b0\u1eddi d\u00f9ng c\u00f3 c\u1ea7n m\u1ed9t \u1ee9ng d\u1ee5ng \u0111\u1eb7c bi\u1ec7t \u0111\u1ec3 qu\u00e9t c\u00e1c m\u00e3 n\u00e0y kh\u00f4ng?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"Most professional SSO implementations require a specific corporate u005cu0022Authenticatoru005cu0022 app or a managed company application. Using a dedicated app ensures that the scan is performed by a trusted device and that the data is handled within a secure, encrypted environment rather than through a generic consumer camera app. Protect your business from credential-based attacks by modernizing your authentication flow.
