Two-factor Authentication (2FA)

Two-factor authentication (2FA) is a security measure that requires users to provide two forms of identification when logging into an account. In the context of cryptocurrency, 2FA can be used to protect user accounts on cryptocurrency exchanges, wallets, and other platforms that hold digital assets.

One common form of 2FA is a one-time passcode (OTP) sent via text message or generated by an app on a user’s smartphone. Another form of 2FA is a physical security key, which is a small device that plugs into a computer or mobile device.

Using 2FA can greatly increase the security of your crypto accounts, as it makes it much more difficult for hackers to gain access to your data.
