Think of your first factor as the lock on the front door of your house and the second factor as the door's deadbolt. The first factor is your Passport York password, and the second factor is a push notification, a code or call sent to your cellphone or a physical security key inserted into your computer. Two-factor authentication is the most effective way of protecting both your credentials and the resources you access with those credentials. With two-factor authentication, you can ensure that all your data remains safe, even if your password is compromised.<\/p>\n\n\n\n<p><strong>Why Do I Need This?<\/strong><\/p>\n\n\n\n<p>Two-Factor authentication adds an additional layer of protection to your accounts and the data you access through them. The easiest way for malicious hackers and phishers to access York's systems and data is by hijacking your account. With two-factor authentication, you are protecting yourself and your community against these sorts of attacks and ensuring each link in our security chain is strong.<\/p>\n\n\n\n<p><strong>How Does It Work?<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Enter your Passport York username and password<\/li>\n\n\n\n<li>Use one of the Duo Supported Devices to verify your identity<\/li>\n\n\n\n<li>You are securely logged in<\/li>\n<\/ol>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"2FA Orientation Video for 快播视频\" width=\"1333\" height=\"1000\" src=\"https:\/\/www.youtube.com\/embed\/tEhPx-2HHNY?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>When will I be prompted to authenticate with 2FA?<\/strong><\/p>\n\n\n\n<p>After you complete your 2FA Setup, you will be prompted to authenticate with 2FA every time you log in to Passport York web services and Office 365.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>When will 2FA be activated?<\/strong><\/p>\n\n\n\n<p>Active Staff, Faculty and Students have been activated for 2FA as of April 2021.<\/p>\n\n\n\n<p>New Students, Staff and Faculty members&nbsp;are activated on a daily basis.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Duo Mobile Compatible Devices<\/strong><\/p>\n\n\n\n<p>To use Duo Mobile, you will need either an Android or iOS device.
