Best Practices for Using One YubiKey for Multiple Accounts

I can say that it’s definitely possible to use the same YubiKey for unlimited sites and accounts.

Types of YubiKeys That Support Multiple Accounts

Before we get started, it’s important to note that not all YubiKeys support multiple accounts.

However, most YubiKeys that support WebAuthn do.

Some of the YubiKeys that support WebAuthn include:

  • YubiKey 5 NFC
  • YubiKey 5C
  • YubiKey 5Ci
  • YubiKey 5 Nano

How to Set Up Your YubiKey for Multiple Accounts using WebAuthn for Unlimited Sites

To use the same YubiKey for unlimited sites and accounts, you’ll need to use WebAuthn. Here’s how to set it up:

  1. First, make sure your YubiKey is set up for WebAuthn. You can do this by following the instructions provided by Yubico.
  2. Next, log in to the website or service you want to use your YubiKey with.
  3. Look for the option to add a security key or enable two-factor authentication. Select this option.
  4. Follow the instructions provided by the website or service to register your YubiKey. This will typically involve inserting your YubiKey and pressing a button.
  5. Once your YubiKey is registered, you’ll be able to use it to log in to the website or service.
  6. Repeat steps 2-5 for all the websites and services you want to use your YubiKey with.

That’s it! With WebAuthn, you can use the same YubiKey for unlimited sites and accounts. Just make sure to keep your YubiKey in a safe place and don’t share it with anyone else.

How to Log In Using Your YubiKey for Multiple Accounts

When you use your YubiKey for authentication, you’ll need to insert it into your device and press the button on the key. Once you do that, the YubiKey will generate a one-time password (OTP) that you can use to log in to your account.

How to Add or Remove Accounts on Your YubiKey

If you want to use your YubiKey with multiple accounts, you’ll need to add each account to the key. To do this, you can use the Yubico Authenticator app. The app allows you to add and remove accounts from your YubiKey, and it also lets you manage your TOTP codes.

To add an account to your YubiKey, you’ll need to open the Yubico Authenticator app and insert your YubiKey into your device. From there, you can select the option to add an account and enter the information for the account you want to add. If the account has a QR code, you can use the app to scan the code and automatically add the account to your YubiKey.

If you want to remove an account from your YubiKey, you can do so by opening the Yubico Authenticator app and selecting the account you want to remove. From there, you can select the option to remove the account from your YubiKey.
