Update to 2FA"},"content":{"rendered":"<p class=\"paragraph\"><span class=\"normaltextrun\">2-Factor Authentication&#8217;s phone call method is a security feature that adds an extra layer of protection to online accounts. 2-factor authentication can be performed by using the Authenticator app, SMS text message, or by receiving a phone call at Chapman University.<\/span><\/p>\n<p class=\"paragraph\"><span class=\"normaltextrun\">Today, the Information Systems and Technology (IS&amp;T) team is <b><u>announcing that the phone call option will be disabled as a form of authentication on May 03, 2023. <\/u>If you do not perform 2FA by receiving a phone call, then you may ignore this announcement.<\/b><\/span><\/p>\n<p class=\"paragraph\"><span class=\"normaltextrun\">Although only a few 2FA requests at\u00a0Chapman University utilize the phone call method, they have proven to be a primary choice for outside attackers to try to circumvent the security on our accounts, as they will trigger multiple\u00a02FA call requests until the user finally approves the request to get the calls to stop, consequently giving them access to their account.<\/span><a href=\"https:\/\/blogs.chapman.edu\/information-systems\/wp-content\/uploads\/sites\/68\/2023\/04\/2FA-4B.jpg\" rel=\"attachment wp-att-3078\"><img loading=\"lazy\"
