This is not just a suggestion but already implemented by BK8 I have tried it even though there is still a problem with delay on security code
For email I use double security activate 2 Authenticators on account and email so not to worry so far safe at least for the last 5 years
After all I never leave a balance in the casino account if i win i will definitely withdraw.
I thought you are suggesting about 2FA as afaik there is no 2FA in bk8 unless I do not know how to activate it.
Afaik the only needed code is when we want to add withdrawal address.
In case of account hacked, the hacker can add their crypto address by contacting support of not receiving the code by sms.
Let me know if 2FA is already available and I'll activate it asap to increase the security of my bk8 account.
