What does it mean that the third party wants to read the verification code sent to me by the piggy bank loan?

Third-party software for piggy bank loans can read the meaning of short messages.

You and the mobile phone manufacturer are Party A and Party B, and other apps or other mobile phone programs are called third parties. It means that the third party is forbidden to read SMS authentication, that is, only you can see the authentication SMS received on the mobile phone, and the software that comes with the mobile phone can be read, but other software can't. Some people will open this permission, because if you choose not to prohibit it, the third-party software of piggy bank loan can read the short message and fill in the verification code after receiving the verification short message. If reading is prohibited, you must fill in the verification code yourself or copy it yourself.
