Repeat Passwords: I was just surfing through the forum a few minutes ago and saw a post where a guy managed to hack an ICO website and contacted the admins and the admins just don't care, never repeat passwords in two websites so that if a hacker manages to get their hands on one of your passwords, they would not be able to affect your funds in other platforms.
This is one important point. In the world of crypto and other things connected to the internet, we have to divide up several things. Main account and backup account, including password usage. This is for the security of your data. If you use the same password for all important accounts, then if one of your accounts can be hacked then it will endanger the others, as OP explained. Backup email is used to register on the website or other things that are public and not too important so that access to your primary email is completely clean from other activities. Don't forget to prepare a special notebook to record emails and passwords and other things that make it easier for you to organize your account.
This is really a good reminder to everyone here because it is one of the most common reasons I think why we are losing some funds. To think of it that we should make a different password per website, it is such a hassle right? So we are making the same password at different websites. But to think of it that our funds are at stake, we should not think that it is a hassle. We should make different passwords per website or account so that you can prevent hackers to get your account and your funds. It is just a simple task but it is important, we are all thinking that the problem is simple but in the reality, there are lots of people being hacked and not only that because hackers can hack it when the password is the same.
