What is two-factor authentication in cryptocurrencies?

Two-factor authentication in cryptocurrencies is a two-step verification of user data to provide additional account protection. For verification, user-generated information, which includes a password, as well as personal data, such as a phone number or email address, and biometric data, such as fingerprints, are used. To ensure maximum account security, you must configure at least two data verification steps. For example, Binance offers to use a security key, Google or Binance authentication, mobile phone (SMS), and email.
