Can I use a YubiKey with multiple devices?

You can use a single YubiKey to log in to numerous accounts across multiple devices. In other words, you can set up your YubiKey for an account via your Windows PC, then use it to log in to that account on mobile or Mac. However, using a YubiKey with multiple devices is dependent on cross-device compatibility . Some models can only work with desktops, while some work with all operating systems.

Does YubiKey store your information?

YubiKeys don’t store any personally identifying information about you. So anyone who gets hold of your YubiKey can’t know what accounts it’s for, see your account usernames, recent activity, or anything of the sort.

Are YubiKeys worth the cost?

YubiKeys aren’t for everyone, but if you’re concerned about security, work in highly data-sensitive organizations, or are in any way a tempting target (like if you own lots of crypto or are a public figure), they’re definitely worth it. They don’t store any of your information, aren’t connected to the internet, and generate all the codes needed for authentication on-device. This makes them very challenging to hack , and the codes on your YubiKey can’t be cloned to another key.

How do I choose the right YubiKey model for my needs?

The first step to choosing the right YubiKey model is ensuring it works with all your devices. Some YubiKeys only have a USB slot, which might make them incompatible with mobile devices and Macs. Likewise, look for supported authentication protocols to see if it matches what’s obtainable on the accounts you use — after all, not all online accounts support security key authentication just yet. Finally, consider extra security features, such as fingerprint scanning, that might make a difference for you.

Can I use YubiKey with my mobile phone?

You can use certain YubiKey models with your Android and iOS smartphones. These mobile-friendly YubiKeys, such as the YubiKey 5 series , validate your logins when you plug them into the device’s charging port. They also support NFC technology — simply tap your key against any device that lacks a USB-A port.
