We’re proud to announce the availability of a new security feature for both AeroFS Hybrid Cloud and Private Cloud: two-factor authentication (2FA)!

What is Two-Factor Authentication (2FA)?

Two-factor authentication lets you add an extra layer of security to your AeroFS account. If you enable 2FA, whenever you log in to your account, you’ll be prompted for your normal login credentials, as well as a 6-digit authentication code you read off your phone or other mobile device. With 2FA enabled, even if an attacker steals your password, or gains access to your email account, they still won’t be able to log in to AeroFS without also having access to your phone.

How can I set up 2FA?


  • Scan the QR code or type in your secret (depending on the app you’re using):

  • Enter the first 6-digit code from your mobile device to enable 2FA on your account.

  • Download and print your backup codes, and keep them in your wallet or somewhere safe.

In the event you don’t have your mobile device with you, you can sign in with a backup code. Backup codes are single-use authentication codes that you should print and keep in your wallet to keep you from getting locked out of your account. In addition, your admin can turn off 2FA for your account if you find yourself completely locked out and failed to download or print your backup codes.

Is this available for the Private Cloud?

Yes! Private Cloud appliance administrators will be delighted to hear that this feature requires no third-party service integration, and in most cases, no additional appliance-side setup either. Your users can set up and use 2FA as soon as you upgrade your appliance to 0.8.61 or newer. For those of you running the appliance behind a tighter outbound firewall, you can configure the appliance to use your company’s internal NTP server to keep accurate time, so your appliance and users’ devices will agree on authentication codes.

Ready to give it a shot? Enable two-factor authentication on your account today.
