Overview

Two-factor authentication increases the security of your CrashPlan for Small Business environment by requiring users to provide additional verification before accessing the administration console or CrashPlan for Small Business mobile app.

Requirements

Two-factor authentication uses the Time-based One-Time Password (TOTP) algorithm and a 160-bit secret key for each user. We officially support and recommend the Google Authenticator mobile app.   

Considerations

  • Two-factor authentication affects access to the administration console and CrashPlan for Small Business mobile app. It does not affect access to the Code42 app on user computers.  
  • To configure this setting, you must sign in to the administration console as a CrashPlan for Small Business administrator user

Enable or disable two-factor authentication

  1. Sign in to the administration console.
  2. Select Settings > User Account Settings.
  3. In the Two-Factor Authentication section, select Enabled or Disabled.
    • Enabled: Requires users to configure two-factor authentication (Google Authenticator is our recommended application). Users must then provide a one-time authentication code in addition to their CrashPlan for Small Business username and password to access the administration console and CrashPlan for Small Business mobile app.
    • Disabled: Users are only required to provide their CrashPlan for Small Business username and password to access the administration console.
  4. Click Save.

User sign in

After enabling Two-Factor Authentication, users are required to set up their account the next time they sign in. (Future sign-ins only prompt users to obtain the verification code from the Google Authenticator mobile app.)

  1. Upon signing in to the administration console, the Set Up Two-Factor Authentication message appears.
  2.  Using the Google Authenticator mobile app, scan the QR code provided (see sample below).
  3. In the Set Up Two-Factor Authentication message, enter the verification code displayed in the Google Authenticator mobile app.
  4. Click Sign In.

Two-factor user setup

Reset a single user's device

If a user loses or gets a new mobile device, follow the steps below to reset the two-factor authentication configuration.

  1. Sign in to the administration console.
  2. Select Users > Active.
  3. Select a user.
  4. From the action menu in the upper-right, select Reset Two-Factor Authentication.
    This invalidates the secret used to generate this user's TOTP and prompts the user redo the initial configuration steps upon the next sign-in attempt.

To reset two-factor authentication for a CrashPlan for Small Business administrator, contact our Customer Champions for support.
