Oppo suddenly sent a short message, all of which were verification codes. What happened? I didn't click on the text message to verify my identity.

Oppo suddenly sent a verification code message, and you didn't have a message to verify your identity.

You don't care about this. Maybe someone else is verifying their oppo account and forgot the password or something else that needs to be verified. Enter the mobile phone number to receive the verification code. Maybe the cell phone number is close to yours, so you entered it incorrectly.

Just like sometimes receiving the verification code from the bank, it should be sent to you because the phone number was entered incorrectly. Keep the verification code safe, just don't let others know casually, and don't click the link on the text message. Anyway.
