Purpose of Knowledge Article:
A guide to how to install the Google Authenticator on your mobile device and set up an MFA token in the Google Authenticator app.
If you use Google Authenticator on your personal or Lab-issued mobile device, Lab policy requires that the device must be configured to use a lock screen (PIN, pattern, fingerprint, etc.).
Resolution:
These instructions must be followed on a computer so that the mobile device can be used to scan a barcode off of the computer's monitor. Try using Google Chrome in Incognito window mode or Firefox in Private window mode if you are having some trouble.
| 1 | On your mobile device, find the Google Authenticator application in the Google Play Store. Install and open the app. |

| 4 | On your computer, go to https://identity.lbl.gov/mfa to add a token and create a barcode. You must generate a barcode at the above link to continue installation.

We recommend including the month, year, and model to easily identify the device. Example: Jay's iPhone 11, August 2020 Click "Add Token." Note, there is a time limit that you must complete this step by. If time has expired, "Cancel" and retrieve a re-issued token. |
