We usually use a "password" on the website to ensure the security of the account.

But most exchanges typically add a two-step verification requirement.

Why do we need two-step verification?

For convenience, most users often set up the same account and password for different Internet services.This could easily lead to someone using the account and password to easily log in to other web services that the user has signed up for after the password has been leaked somewhere.

If you want to compare "password" to "two-step authentication".

Passwords are like "seals." You may use the same seal on different websites, or even someone else may use your seal secretly.

Two-step verification is like a "signature" that only you can use.For such an important safe operation as the withdrawal of currency, it must be "oneself" to be able to operate.
