Securing a Coinbase account using the YubiKey security key should be a priority for anyone using the platform, even if you don’t actively invest or hold any funds. With the increased popularity of cryptocurrency, the threat of accounts takeover is even more real. The inadequate security measures have already affected thousands of Coinbase customers resulting in the unauthorized third party gaining access to their accounts.

Setup the YubiKey with Coinbase by visiting your Security options under your profile settings. Select Security Key and follow the instructions on the screen. Make sure to register two YubiKeys and keep the spare one in a safe place as a backup option.

Between March and May 2021, 6000 Coinbase customers received an email notifying them that they were victims of a third-party campaign to gain unauthorized access to their accounts, which resulted in the loss of any funds located on that account.

The email titled “Unauthorized Access to Your Coinbase Account” describes how the attackers took advantage of the now fixed flow in Coinbase’s SMS Account Recovery process, which, combined with the knowledge of personal details of the account owner, led to the disaster.

It is not clear how the attackers gained detailed knowledge about the Coinbase account owner’s password, phone number, or email, but the suspicion is that the phishing attacks led to the disclosure of this data by the user himself.

All affected accounts were secured with the SMS-based Two-Factor Authentication method. However, the SMS-based Two-Factor Authentication is now widely considered as unsafe and, as such, should be avoided in favor of more secure authentication using time-based-one-time passwords (TOTP) via Authenticator apps like Google Authenticator or by using the Security Key like YubiKey.

Although Coinbase offered a full refund to all affected users, that does not change the fact that you should stop using the SMS-based Two-Factor Authentication and opt for more secure options like YubiKey Security Key or an Authenticator app.

How to setup YubiKey with Coinbase?

Securing your Coinbase account with YubiKey takes only a few minutes, and it will give you peace of mind that you have used the best and most secure method of authentication currently available.

1) Click Settings under your Coinbase profile.

Click the Settings option under your profile user icon at the top right corner of the browser window.

2) Click the Security tab.

Make sure that your primary phone number is up to date. Having your phone number correct is crucial if you ever need to contact Coinbase support to help with account recovery.

3) Make sure to have your YubiKey ready.

Don’t worry if you currently have a Text message or Authenticator option selected as your primary authentication method. Once you finish, the YubiKey will become the primary authentication method, and other options will automatically be disabled.

Many online services allow you to register at least two types of authentication methods at once.

For example, you can have the YubiKey configured as your primary authentication method and the option to authenticate using the TOTP codes generated by the Authenticator app like Google Authenticator.

The idea is that if you lose your YubiKey, for example, you will have a fallback option and still be able to log in using the TOTP codes generated by your authenticator app.

However, Coinbase does not offer a fallback option if you lose your YubiKey.

Therefore, it is essential that if you choose to secure your Coinbase account with YubiKey, make sure to buy two devices and register them both while keeping the spare one in a safe place at home.

I would recommend my personal favorite YubiKey 5C NFC, a very versatile Security Key with the latest USB-C and NFC technology, allowing you to use it with your NFC-enabled devices just by tapping it.

If you are an Apple user, the YubiKey 5Ci is the best next choice, in my opinion. Although it lacks NFC connectivity, it has a dual connector with support for USB-C and Lightning.

Of course, you can also check the whole range of YubiKeys on the Yubico website and pick the one which suits you best.

And finally, if you are unsure which one to select, then take the Yubico quiz, which will help you choose the best option.

4) Press the Select button next to the Security Key option.

6) Read the Security Key restrictions note.

During the YubiKey setup, Coinbase will display a note about potential Security Key restrictions you may encounter when using the Coinbase Pro mobile app.

It will also warn you about using incompatible browsers and the possibility of breaking support for 3rd-party applications which were connected to your Coinbase account.

Press the ‘I understand’ button to continue if you are happy with the restrictions.

7) Confirm settings change with current 2FA method.

Suppose you had another type of Two-Factor Authentication configured before. In that case, you might need to confirm the settings change by retyping the code sent to you via SMS message or the code generated by the Authenticator app.

Press ‘Confirm’ when ready to continue.

2) Press Add another security key button.

Press ‘Add another security key’ to continue.

Option to add a second YubiKey.

Do not remove your first Security Key until asked, as the process requires authentication before you can add another key.

Then, make sure to remove your primary key and insert the spare one before registration.

Follow the steps as before to register the second key.

When finished, you should be able to see both keys under the Manage Security Keys section.

Which YubiKey works with Coinbase?

Although I don’t own all the YubiKey types, I own four most recent USB-C models, and I can confirm that they all work with Coinbase.

I would recommend my personal favorite YubiKey 5C NFC, a very versatile Security Key with the latest USB-C and NFC technology, allowing you to use it with your NFC-enabled devices just by tapping it.

If you are an Apple user, the YubiKey 5Ci is the best next choice, in my opinion, which according to the works-with-yubiKey catalog, should also work with Coinbase.

If you decide to secure your Coinbase account with Security Key, read about the restrictions that will apply when using this technology.

Do you need two YubiKeys?

Although you can register only one YubiKey with Coinbase, it is highly advisable to register a second one. The second YubiKey will act as a backup option in case you lose your primary YubiKey security key.

Keep your spare YubiKey in a safe location at home.

Does YubiKey work with Coinbase Pro?

Both Coinbase and Coinbase Pro are secured using the same account credentials. If you secure your Coinbase account with YubiKey, you will automatically secure your Coinbase Pro account with the same type of authentication.

Keep in mind that as of writing this article, the Coinbase Pro mobile app does not support security keys yet, so you won’t be able to sign in to it if you add the security key.
