The Best Security Keys for Multi-Factor Authentication

Losing access to your online accounts or getting hacked can get you or your business into grave trouble. Fortunately, we keep seeing improvements in digital security and the technology around it. From seamless passwordless logins to security keys and MFA (multi-factor authentication), it’s now possible to secure your online accounts against various attacks.

There are many ways to implement Multi-factor Authentication (MFA) or Second-factor Authentication (2FA), but one of the easiest is using a security key. These small devices that can fit in your pocket become a physical barrier to accessing your accounts. Just like opening a physical lock, you will need to insert the key to open the lock and safeguard your assets from any potential attack.

Important reminder when setting up security keys

Depending on the platform or service where you plan to use your security keys, it’s important to understand that the use of the security key will be necessary for any new login or devices, meaning you could potentially lose access to your accounts if you lose the key. This is why it’s always recommended to have at least one backup security key in case of an emergency. The best practice would be to have that backup offsite on a secure location, some users even prefer to have 3 keys, one to keep at hand at all times, another at home or the office and a third offsite on a safe location (with a family member, trusted friend, secure vault, etc). In the case of Google accounts, losing all security keys linked to an account would result in losing the account, other platforms may offer an alternative recovery depending on their policy.

We are going to save you some time and give you our top recommendations when it comes to the best security keys for multi-factor authentication.

Tips for Security keys

Security Keys and iPads

Apple iPads do not have NFC readers, so you can’t scan the NFC chip like you would with your smartphone.


  • Some platforms will allow your mobile phone as a Passkey. Most modern smartphones have an integrated security key that allows your phone to become a wireless security key. However, support for this varies by platform.

  • Use a Security Key with either USB type C for modern iPads or a Key with Apple Lighting port for older generations. You may also use a USB to Lighting adapter.

Smartphone build-in security keys

Many modern smartphones include a built-in security key, that can be used wirelessly to authenticate your account, similar to a security key. However, the support for these features varies greatly by platform or service. If you plan to use this feature, also remember to set proper lock screen settings (fingerprints are usually the safest) on your phone, since losing it may also compromise the accounts and apps you have on your device.

The Ultimate Key for Digital Security

Security Keys are one of the best methods to add multi-factor authentication (MFA) and secure an online account. However, the best solution for you or your business may vary depending on many factors, from the services you use to the type of devices you own. The best solution can often be different from one user to the next. We recommend contacting an expert on the subject if you are still determining the best route and answer for your needs.
