Enabling 2FA means you need to authenticate your login in two separate ways – the first with your password, the second with a code that is sent to your phone, a code that only you know.
2FA is short for two-factor authentication. This is an extra layer of security that helps protect a user’s DingConnect account. When 2FA is enabled for an account, even if someone knows the username and password, their access will be blocked unless they enter the correct one-time code.
DingConnect uses SMS to provide this one-time code. Each code may be used only once and must be used within three minutes of receipt.
