What happened when Xiao Lan didn't log in and received the information verification code?

There are two possibilities to send verification code without logging in.

The first possibility is that the bank's system is out of order and a verification code will be sent to the user. In this case, the user can call the bank customer service phone to ask.

The second possibility is that the user's information is fraudulently used by others, and others are operating the user's account to log in, causing the system to issue a verification code.
