The Best Practices for Backing Up Your YubiKey

A YubiKey helps protect your online accounts by adding a second layer of security. It works like a physical key that you plug in or tap to prove it’s really you. If you lose it, though, getting locked out of your accounts can be a big problem.

That’s why having a backup plan is so important when using a YubiKey USB. It gives you peace of mind, knowing you won’t be stuck without access.

Get a Second YubiKey:

The easiest and most helpful backup is simply having another YubiKey. You can set up both keys with the same accounts so that either one can be used. Keep one with you and store the backup somewhere safe, like a locked drawer or fireproof box. This way, if your main key gets lost or damaged, you won’t lose access.

Register Both Keys with Each Service:

When setting up your YubiKeys, be sure to register both the main and backup keys with your accounts. Many services let you add more than one security key. Don’t wait until something happens, do this right from the start. That way, the second key is already ready to use if needed.

Label Your Keys:

If you have more than one key, it’s helpful to label them. Write “Main” and “Backup” or use colored key covers to tell them apart. This makes it easier to manage them and avoid confusion later. You’ll always know which one you carry daily and which one stays in your safe place.

Keep Your Backup in a Safe Place:

Your backup YubiKey should be stored somewhere secure, but also somewhere you can find it when needed. Avoid carrying both keys in the same bag or wallet, as losing them together defeats the purpose. Choose a spot that’s dry, private, and easy to remember.

Write Down Recovery Codes (If Available):

Some accounts give you recovery codes when you turn on security key protection. These codes can help you get back in if something goes wrong. Keep them written down and stored safely, just like your backup YubiKey. Never save them on your computer or phone where others could find them.

Losing a YubiKey doesn’t have to be a big problem if you plan ahead. By backing it up with a second key and storing it safely, you stay ready. These simple habits help you keep your accounts safe while avoiding stressful lockouts.
