What if i lose my yubikey

What if i lose my yubikey

2 factor authentication explained

I recently misplaced my bag, which included everything from my residency card, driver’s license, credit cards, cash cards, various ID cards, and, last but not least, my Yubikey NEO. Being in Japan, I expected the purse to appear in a few days, with the money missing but all the cards intact. This time, however, that is not the case. So, after reissuing the majority of the cards, I also went through the required steps with the Yubikey, which housed my GnuPG subkeys and was used as a second factor for a number of services (see here and here).
Despite the fact that the Yubikey’s GnuPG keys are considered secure from extraction, I decided to revoke them and build new subkeys – one of the major advantages of subkeys is that you don’t have to start from zero and instead create new subkeys instead of trying to get signatures again.
All of this is fairly self-explanatory: Use the gpg —expert —edit-key command. YOUR KEY ID, then press N to select the subkey, then press R to select the revkey. You can pick all three subkeys and revoke them all at once by typing key N for each of them (where N is the index starting from 0 of the key).

In the event of a misplaced YubiKey, I will now cancel or press escape. The screen then abruptly switches, and the “Troubleshoot MFA” connection vanishes! Furthermore, when the message appears, I am unable to click on it.
The only general response is that you should generally contact the support team for the specific site. Different businesses would almost certainly have different policies and processes in place for recovering accounts.
I found in the AWS documentation that each account is only given one Key. One solution is to create a second account for that VM and approve it with your second key. Perhaps the root user gets your “backup” key, which you hold in a safe when using a delegated account, as well as your “usual” key…

For the time being, we are unable to do so due to security issues. To switch between two-factor authentication protection levels, you must first disable and then allow two-factor authentication for your account. There’s more on that here.
Depending on the model, you can need to trigger the key by pressing the button or gold disk on the top of the key – this is the case for YubiKeys, for example. U2F security keys, on the other hand, are not a biometric system. A simple tap on these security keys unlocks the key with a small electrical charge.
The authentication of U2F security keys with a button or gold disk will be completed with a small tap. For more details, please see the video at the top of the page. If your U2F security key doesn’t have a button or a gold disk, you’ll have to unplug and re-plug it anytime authentication is needed.
One explanation for this is that the Chrome browser is the only one that supports U2F. Firefox is expected to embrace this soon, and other browsers will undoubtedly follow suit, making U2F open to the vast majority of internet users. Furthermore, establishing new global standards requires time. Visit Yubico’s website for more information.

Except for a couple of points, I like this approach. First, what happens if I misplace (or get my Yubikey stolen)? What do I do if I don’t have my Yubikey (at my parents’ house), which is a more practical problem?
I have two Yubikeys, each with its own SSH key created and signed by an offline master on a USB key held in a safe. I simply revoke/expire the key on keyservers and create a new one using the offline key if I lose one. If you don’t have your Yubikey with you, maybe you should spend time with your parents instead of focusing on items that need an SSH key?
You won’t be able to withdraw money from your account if you don’t have your ATM card. You can’t drive if you don’t have your car keys. This is absolutely ideal. Yubikeys are tiny and durable; simply attach them to your (physical) keychain. If you lose your yubikey, make sure you have a backup yubikey or backup the keys stored on the yubikey so you can build a new one. If you use a solution that prevents the secret from escaping the key (such as Fido U2F keys), make sure to register your backup key for all of the services you use, or create recovery codes for each one. Needless to say, these must be held in a safe spot.
