2FA is very important because sometimes I show my login password gotten anyone and he login in website, specifically when I save my password in Google chrome it’s Somehow password Lick so 2FA is best way to saved account.
2FA is the best way to secure your accounts and websites login information but not for crypto wallet, you need to learn more about centralized wallets and none centralized wallet, if you see any crypto wallet that allows 2FA just know that your keys aren't completely yours.
