Falcon 2-Factor Authentication

The next page is where you’ll enter your desired method for 2-factor authentication. We recommend Google’s Authenticator app. However, Duo Mobile, WinAuth, and JAuth will also work.

Google Authenticator is available in the app store for both iOS and Android

The password screen appears first, followed by the screen where you select a method of 2-factor authentication

Step 2: Download and install the agent

Upon verification, the Falcon UI will open to the Activity App.  To download the agent, navigate to Host App .Then select “Sensor Downloads.”  

Sensor download page

The downloads page consists of the latest available sensor versions.  Select the correct sensor version for your OS by clicking on the download link to the right. At the top of the downloads page is a Customer ID, you will need to copy this value as it is used later in the install process.

Finally, verify that newly installed agent in the Falcon UI. To view a complete list of newly installed sensors in the past 24 hours, go to https://falcon.crowdstrike.com.

Navigate to: Events App > Sensors > Newly Installed Sensors

The hostname of your newly installed agent will appear on this list within five minutes of installation. If you don’t see your host listed, read through the Sensor Deployment Guide for your platform to troubleshoot connectivity issues.

Conclusion

The resulting actions mean Falcon is active, an agent is deployed and verified, and the system can be seen in the Falcon UI.
