Two-Factor Authentication (2FA) adds an extra layer of security to online accounts, especially those related to cryptocurrency. It requires not only a password and username but also something that only the user has on them, such as a mobile device. When logging in, after entering the usual credentials, users must provide a second form of verification. This can be a text message with a code, an email, or an authentication app like Google Authenticator. This additional step significantly reduces the risk of unauthorized access. If someone obtains your password, they would still need this second factor to gain access. This makes it much harder for hackers to compromise accounts, safeguarding digital assets. Overall, 2FA is a crucial practice for anyone handling cryptocurrency, helping to protect against theft and fraud. By combining something you know (your password) with something you have (the second factor), it creates a more secure environment for transactions and account management.
