If you're looking to Download Epic Authenticator on your Chromebook laptop Then read the following guideline.

The Epic Authenticator app provides two-factor authentication for your Epic electronic health record system. Two-factor authentication makes your Epic credentials more secure by requiring another step to verify that it's you when you log in. Periodically when logging into Epic you'll receive a notification on your phone. Tap the notification to indicate that it's you and finish logging in. In case you miss the notification, you can also log in by typing in a temporary passcode displayed in the Epic Authenticator app. Your organization must set up Epic two-factor authentication before you can use the app, and you'll need to enroll your Epic Authenticator device in Epic. To get started, refer to the directions provided by your organization, or contact your organization's help desk.
