Two-factor authentication (A2F) significantly enhances account security by requiring users to provide two forms of identification. A2F comes in various forms, including SMS verification codes, authentication apps, and biometrics. In the face of online threats, A2F has become essential, especially in the Crypto Assets sector. When choosing the appropriate solution, it's important to consider the level of security and device availability. Once configured, it should remain updated and monitored to ensure ongoing protection of account security.
