Two-Factor Authentication (2FA) is a security measure that adds an extra layer of protection when accessing accounts or making transactions. It requires users to provide two different forms of identification before gaining access.The first factor is usually something the user knows, like a password. The second factor is often something the user has, such as a smartphone app that generates a time-sensitive code or a text message with a verification code. This makes it harder for unauthorized individuals to access accounts, as they would need both the password and the second factor.In the cryptocurrency space, implementing 2FA is crucial due to the risks associated with hacking and fraud. Many platforms and wallets offer this feature, urging users to enable it for increased security. By using 2FA, individuals can better protect their assets and sensitive information from potential threats, providing peace of mind in an often volatile environment.
