Enabling two-factor authentication by security key

Find out how to secure your OVHcloud customer account by enabling two-factor authentication via U2F security key

Last updated 8th July 2022

Objective

Two-factor authentication via Universal Second Factor (U2F) is one of the methods offered by OVHcloud to help you secure access to your account. This security technique via USB key is hosted by the FIDO Alliance, and is becoming increasingly popular for two-factor authentication in many domains.

This guide will show you how to enable two-factor authentication via U2F security key, and understand how to use it in future when you log in to the OVHcloud Control Panel.

Requirements

Instructions

Addition of a new U2F key on recent versions of Chrome/Chromium

Adding a new U2F key is currently no longer possible on recent versions of the Chrome browser (starting with Chrome v98) and its derivatives such as Chromium.
The use of a U2F key already added and functional is always possible on these recent versions of the browser, only the addition of a new U2F key is impossible.

Our teams are working to resolve this issue. Pending a final resolution, we invite you to follow one of these two workaround methods:

  • Use another browser (such as Firefox) to add your new U2F key, then use your regular Chrome/Chromium browser to log in to the OVHcloud Control Panel as usual.
  • Manually re-enable U2F support in your Chrome/Chromium browser. To do this, as in the image below, copy this value chrome://flags/#u2f-security-key-api into the browser's address bar, select Enabled from the right-hand drop-down menu and restart your browser.

Once the key has been recognised, you can also add a description. This may be useful for identifying people who are likely to use this identification method on your account.

Step 4: Save the emergency security codes.

When you first add a two-factor authentication security method, you will be sent emergency codes. Please ensure that you store these codes in a safe place. We advise saving them in a password manager.

You can delete or regenerate them via the OVHcloud Control Panel.

As a reminder, please note that it is important to save these emergency codes and ensure that they are valid. If one of the security methods you have selected becomes unavailable (theft or loss of your mobile phone or security key), access to your account may be blocked.

Step 5: Log in to the OVHcloud Control Panel via two-factor authentication.

Once you have enabled two-factor authentication, the login screen will offer you one of your security methods. If you would like to use another method, click Try another method.

All of the choices you have enabled will then appear.
