I see. Strange then that I have to confirm a withdrawal through 2 outlets. I mean 2fa is the safest way anyway because an email account can be hacked easily. So confirming with email alone is much more unsafe than having 2fa activated, and then 2fa requires another verification, I don't get it.
Your gambling account can be hacked, your email account can be hacked.
If you can use 2FA for both your gambling account and your email account, you reduce risk of double hacks a lot and risk of losing your fund in an gambling account is smaller considerably.
2FA is a second layer of security protection for your accounts, and first layer is your account password on gambling site and email. Passwords need to be strong enough.
[GUIDE] How to Create a Strong/Secure PasswordYou seem to have misread what I was writing here. It's obvious that 2fa is the safest, that's why I don't understand that additionally they want an email verification, that in my and some others, doesn't send the email you need to request the transaction.
Everybody here knows what 2fa is, so there is no further explanation necessary.

Anyway, thanks for your input.
