What is Two-Factor Authentication (2FA)?
Two-Factor Authentication (2FA) is a security verification method that requires two forms of identification.
When logging in, you must enter your login password as the first factor, followed by a 2FA code (SMS verification code, TOTP dynamic password, or passkey) as the second factor. This adds an extra layer of protection to your account. For security reasons, 2FA will be enabled by default after binding your phone, TOTP authenticator, or passkey to your account.
