透過 Google Authenticator 取得驗證碼

hi @RONG ,welcome to MetaMask community.

MetaMask is a non-custodial wallet. Unlike centralized services, your wallet is not controlled by any company. Once you have the seed phrase or private key, you are in full control of the wallet, so 2FA is pointless

MetaMask 是个非托管钱包。 与中心化服务不同,你的钱包不受任何公司控制。 一旦获取了助记词或私钥,你就可以完全掌控了这个钱包,所以二次验证是没有意义的。

Here is a more detailed explanation.
