The user scans this with an authenticator app, which stores the secret on the device. At login, the app and the server independently compute a 30-second passcode from that secret and the current time. Because the code is time-bound and device-bound, intercepting it in transit provides no lasting value to an attacker.","inLanguage":"vi"},"inLanguage":"vi"},{"@type":"Question","@id":"https:\/\/pageloot.com\/blog\/qr-codes-enhance-pam-authentication\/#faq-question-e14cc11ce0c0","position":2,"url":"https:\/\/pageloot.com\/blog\/qr-codes-enhance-pam-authentication\/#faq-question-e14cc11ce0c0","name":"R\u1ee7i ro b\u1ea3o m\u1eadt l\u1edbn nh\u1ea5t c\u1ee5 th\u1ec3 \u0111\u1ed1i v\u1edbi vi\u1ec7c \u0111\u0103ng k\u00fd MFA d\u1ef1a tr\u00ean m\u00e3 QR l\u00e0 g\u00ec?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"The enrollment QR code vulnerability is the most commonly overlooked risk. The TOTP secret embedded in an enrollment QR code does not expire on its own, so any screenshot, email forward, or backup copy of that code remains usable indefinitely. Mitigate this by configuring enrollment codes to expire after a single successful scan, and audit your email and backup systems to purge any stored historical enrollment codes.","inLanguage":"vi"},"inLanguage":"vi"},{"@type":"Question","@id":"https:\/\/pageloot.com\/blog\/qr-codes-enhance-pam-authentication\/#faq-question-aec22cd4e0bd","position":3,"url":"https:\/\/pageloot.com\/blog\/qr-codes-enhance-pam-authentication\/#faq-question-aec22cd4e0bd","name":"Khi n\u00e0o t\u00f4i n\u00ean s\u1eed d\u1ee5ng m\u00e3 QR \u0111\u1ed9ng thay v\u00ec m\u00e3 t\u0129nh trong m\u00f4i tr\u01b0\u1eddng PAM?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"Always prefer dynamic QR codes for authentication and MFA enrollment flows. Dynamic codes can be revoked instantly if a device is lost, updated without redistributing physical materials, and monitored with real-time analytics. Static codes are appropriate only for low-risk, read-only content where instant revocation and audit logging are not required.","inLanguage":"vi"},"inLanguage":"vi"}]}},"_links":{"self":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/47962","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/users\/17"}],"replies":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/comments?post=47962"}],"version-history":[{"count":6,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/47962\/revisions"}],"predecessor-version":[{"id":54978,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/47962\/revisions\/54978"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/media\/54090"}],"wp:attachment":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/media?parent=47962"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/categories?post=47962"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/tags?post=47962"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
