What Is a Security Key on Coinbase?

A security key is a physical device that is used to authenticate a user’s identity and authorize transactions. It is a hardware-based security token that provides a higher level of security than a software-based security token, such as a password.

A security key is typically used in conjunction with a software-based security token, such as a password. The security key adds an additional layer of security by requiring the user to possess the physical device in order to access the account or perform transactions.

The use of a security key can be helpful in preventing unauthorized access to an account or data, as well as fraud or theft. For example, if a hacker were to obtain a user’s password, they would still need the physical security key in order to gain access to the account.

There are several different types of security keys available, including USB keys, smart cards, and tokens that are worn on the body. The type of key that is best for you will depend on your needs and preferences.

USB keys are the most common type of security key. They are small devices that can be plugged into a computer’s USB port.

USB keys typically come with a software program that must be installed on the computer in order for the key to work.

Smart cards are similar to credit cards and contain an embedded computer chip that stores information about the cardholder. Smart cards can be used with a card reader to authenticate the user’s identity and authorize transactions.

Tokens that are worn on the body, such as bracelets or pendants, are also available. These devices usually contain an NFC chip that can be read by an NFC-enabled device, such as a smartphone.

The NFC chip stores information about the user’s identity and can be used to authenticate the user and authorize transactions.
