Two-factor authentication (2FA) is the second layer of security that protects your account or system. Users must go through two layers of security before accessing their account. 2FA increases the security of online accounts by requiring the user to provide two types of information such as a password or PIN, email account, card or fingerprint before the user can log in. The first factor is the password, the second is the additional factor.

2FA is designed to prevent unauthorized users from gaining access to your account using only a stolen password.

Despite the slight inconvenience of a longer login process, security experts recommend enabling 2FA wherever possible: email accounts, password managers, social media apps, cloud storage services, financial services, blogging platforms, and more. Apple account holders, for example, can use 2FA to ensure they are only accessed from trusted devices. If a user tries to log into their iCloud account from another computer, they will need the password, but also a multi-digit code that Apple will send to one of the user's devices, such as your iPhone.

2 Factor Authentication (2FA) is a method of authentication that requires two different verification factors to confirm the user's identity. The first factor is usually a traditional password, and the second could be a code generated by a mobile application or sent to the user's phone. With this additional security measure, even if a criminal obtains the password, they will not be able to access the account without possessing the second verification factor. 2FA provides an extra layer of security because it requires a potential intruder to have additional knowledge or physical presence with the second authorization factor. This way, even in the case of a password leak, the account will still be protected from unauthorized access. In this way, users can feel safer using online services, such as cryptocurrency exchanges.
