What are Yubi Keys?

Yubi Keys are hardware-based security tokens that provide an extra layer of protection for your online accounts. They work by generating a key pair for each site a key is registered at that is required in addition to your username and password when logging in. This means that even if your username and password are compromised, attackers would also need physical access to your Yubi Key in order to gain access to your account.

What are Yubi Keys used for?

Yubi Keys can be used for a variety of applications, including logging into online accounts, encrypting/decrypting files, and signing digital documents. They can also be used as an extra layer of security for 2-factor authentication (2FA) and 2-step verification (2SV) systems.

Yubi Key alternatives?

There are a few other hardware-based security tokens on the market, such as Google's TitanSecurity Key and Microsoft's Azure Authenticator Device. However, Yubi Keys are one of the most popular and widely-supported options.

Pros/Cons of Yubi Keys?

Some pros of using Yubi Keys include increased security for online accounts, convenience (since they can be used for multiple applications), and portability (they can easily be carried with you on a keychain or in your wallet). Some potential cons include the initial cost of purchasing a Yubi Key (which can range from $20-$50 USD), and the fact that you would need to have your Yubi Key with you in order to use it. Additionally, if you lose your Yubi Key or it is stolen, anyone who finds it would have access to any of the online accounts that are protected by it.
