The difference between verification code and dynamic verification code in English is as follows:

1、Verification code: This is a code used to verify the identity of a user or to confirm the authenticity of a transaction. It can be static or fixed, and is often used in various online registration or login processes.
2、Dynamic verification code: This is a type of verification code that changes frequently, often every few seconds or minutes. It is generated automatically and is typically used to provide additional security for online transactions or accounts. When a user requests a dynamic verification code, they will receive a unique code that they must enter to complete the transaction or access the account. This adds an extra layer of security because even if someone knows the user’s password, they will still need the dynamic code to complete the action.
In English, the main difference between these two types of verification codes is that dynamic verification codes are constantly changing, while static verification codes remain fixed. Dynamic codes provide higher security than static codes because they are more difficult to intercept or steal.
