What is an authentication code?
An authentication code is a number generated by the authenticator app on your mobile device for use as multi-factor authentication. To retrieve this code, launch the authenticator app from the same device you initially configured your multi-factor authentication. If you have multiple site authentications within the app, the listing for this site should contain your username and web address.
What is multi-factor authentication?
Multi-factor authentication is a layer of security designed to prevent someone from accessing your account, even if they have your password. Multi-factor authentication requires you to verify your identity using a random sequence of six numbers. You can choose to have this security code sent to your mobile phone or alternate phone number. Each security code is used only once. It is not a password that you need to create and remember.
Why am I being asked for this?
Multi-factor authentication has been made required by the administrators in an effort to increase security for the account.
What if I am unable to provide my authentication code?
Your admin can reset your multi-factor configuration so that on your next login you'll be instructed to download the app and scan the QR code so you will be able to provide the code with your current mobile device.
