Support for registering multiple security keys (2024)

FAQs

Can you use a security key for multiple accounts? ›

A security key is a hardware-based device that plugs into a computer to simplify two-step authentication. When prompted to authenticate, you simply tap the physical key. There's no need to use your smartphone, and the same security key can be used on multiple devices.

Most people should have at least two security keys: one for everyday use and a backup key that can stay somewhere secure, such as in a safe, if you lose your everyday key. Some people may want additional keys for different devices. Additionally, the security key ecosystem has some rough edges.

Physical security keys provide extra protection for your Apple ID against phishing attacks. A security key is a small external device that looks like a thumb drive or tag, which can be used for verification when signing in with your Apple ID using two-factor authentication.

This is your free additional layer of security at login. In addition to your password, you'll enter a One-Time PIN (OTP) that's unique for each login attempt.

YubiKey recommends having more than one token to reduce the risk of being locked out of your account because of token loss. You can link up to 5 YubiKey tokens with your account.

We at Yubico always recommend having more than one YubiKey. This way, one key can be used as a primary key, and the other can be used as a spare. Please note that for security reasons, the firmware of our products does not allow stored secrets to be read, meaning it is not possible to “clone” or "duplicate" a YubiKey.

Q: How many spares should I get? A: Many of our customers actually purchase several spares for maximum security and peace of mind. This is not a bad idea when guarding extremely critical accounts. Starting off, you should be fine with 1-2 spare keys.

There are three different kinds of network security keys: WEP, WPA, and WPA2, each more secure than the last. The type of security key you choose, along with how strong your password is, determines how safe your network is from hackers.

The YubiKey itself can hold multiple FIDO2 credentials (up to 25), giving a user enough flexibility to secure all important accounts.

Sign in to the Apple ID website (https://appleid.apple.com) and review all the personal and security information in your account to see if there is any information that someone else has added. If you have two-factor authentication turned on, review trusted devices for any devices that you don't recognize.

How do I unlock my Apple ID for security reasons? ›

Once you are locked out of your account, the only way to regain access is to reset your password. To do that, you'll need to prove who you are by any of the following three: using a trusted device, using the Apple Support app, or logging in to iforgot.apple.com in a web browser.

If you lose or break your security key token, or the battery needs replacement, you will only be able to log into your PayPal account with direct assistance from PayPal until you receive and activate a replacement security key taken.

Should YubiKeys be reused? YubiKeys could be reused. There are a number of considerations that need to be taken into account when deciding on whether or not to reuse YubiKeys. Besides removing and reissuing credentials, tracking systems may need to be updated.

For security, the firmware on the YubiKey does not allow for secrets to be read from the device after they have been written to the device. Therefore you cannot duplicate or back up a YubiKey or Security Key.

If you lose your Yubikey, you can still use your phone authenticator app, but you cannot create a backup Yubikey. However, Yubikey also provides methods to recover your account, so you can get a replacement. An advantage to Yubikey is that it comes on a USB that cannot be identified.

The YubiKey works with Password Safe to protect your passwords using two-factor authentication (2FA). Both a master password and a YubiKey are needed to enable access to your Password Safe file, which contains the usernames, websites, passwords and other information for all of your online accounts.

Use any YubiKey feature, or use them all. The versatile YubiKey requires no software installation or battery so just plug it into a USB port and touch the button, or tap-n-go using NFC for secure authentication.

Can I leave my YubiKey plugged in all the time? ›

Do I need to keep my yubikey plugged in all the time? A. No, you only need to insert your yubikey when you are prompted to do so during login. Leaving it plugged in could result in the yubikey being lost or damaged.

To do this, you will first need to use the Yubico Authenticator app to scan the QR code that was issued to the first security key by the service. Then get the QR code for the second security key. Scan it with the same app and link them that way. After that, you can use any of these keys for authentication.

The counter starts at zero and is incremented each time the device is plugged in. Two bytes for the session counter allows for 2(2*8) = 65,536 sessions. In other words, you can plug in the Yubikey three times a day for almost 60 years before running out of session counters.

The most common types of network security keys are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA/WPA2) .

A single YubiKey works across multiple shared devices including desktops, laptops, mobile, tablets, and notebooks, enabling users to utilize the same key as they navigate between devices, and helping you deploy phishing-resistant MFA at scale.

With these new capabilities, the YubiKey enables the replacement of weak username/password credentials with strong hardware-backed cryptographic key pair credentials.

It is costly to design, mould, manufacture, sell and support a hardware product, even something as small as this. Since you don't want your 2FA company to go out of business there is good value in knowing they have a stable business model that can actually support a company rather than just burning capital.

Can you have 2 factor authentication on multiple devices? ›

To use 2FA, you will need to have an additional device (most often your work or personal mobile phone). When signing into a new device the first time, you will be asked to enter a code that is sent to your secondary device, this ensures that you are the only one who can access your account.
