Why does Coinbase keep sending me a verification code?

If you receive a text message reporting that you’ve received digital currency that you did not authorize, it is likely a phishing attempt . Coinbase does not send out texts to verify transactions.

Coinbase shows you a QR code, which is a representation of the secret key, which you then scan using an Authenticator app on your mobile device . Google Authenticator and several other authenticator apps allow you to generate TOTP codes using your mobile device or computer.

The reason for these verification codes is to confirm that the password to somebody’s account is correct . They were either sent to you by the owner of this account by mistake or by a thief. Since you don’t know which one is which it’s better to throw them away.
