In the above example ("my phone"), the user is trying to generate a token that will be used with the Google Authenticator on a phone. To add a new token, first add a descriptive text in the ' Description' box. Login to your Iris account using your login ID, NERSC password and OTP at. You first create a token in Iris, and then install it on your app. In this step you will "connect" the app on your mobile device to your Iris account. Once configured, you can use the app without any phone or internet service. Please note that you do not need to have a cell phone signal or WiFi to use Google Authenticator since OTPs are generatedusing the internal clock in your device. You can download Google Authenticator for Android on the Google Play Store or Google Authenticator for Apple on the Apple Store. If you do not have such a device, NERSC also supports and provides instructions for Authy, a desktop app for Windows and Mac computers. Other TOTP (Time-based OTP) authenticator apps can work, too - you can search for "TOTP" to find other options. NERSC primarily supports the Google Authenticator app, which runs on an Android or iOS device. Install the token on the authenticator app The four basic steps for configuring your NERSC token are: The one-time password entry in the authenticator app is sometimes called a "token," or more specifically, a "soft token." To use MFA, you create a token for NERSC and install it on the authenticator app. Each password can be used only one time, thus the name "one time password" or "OTP." When you log into an MFA-enabled system, you will enter your NERSC password followed by the OTP displayed on your authenticator app. The authenticator presents a 6-digit password that changes every 30 seconds. MFA at NERSC makes use of an app that you install on your mobile device, which you configure through Iris (If you do not have an iOS or Android mobile device, see below for alternatives). As the name implies, you can use an OTP only once. With NERSC's MFA, you authenticate using your NERSC password plus a "one-time password" (OTP). MFA provides greater protection than regular passwords against phishing and other modern threats to your digital security. NERSC users are required to use Multi-Factor Authentication ( MFA) for logging into NERSC resources. Multi-Factor Authentication (MFA) ¶ Introduction ¶
