2. One single password for everything: 10 signs you should invest in your personal cyber security

2. You have one single password for all or almost all your online accounts

In the last months many services were hacked and email addresses and password hashes (sometimes passwords in plain text) were stolen. This allows hackers to reverse engineer your password and use it to access all other services you use.
This is why it is important to have unique passwords for each online service. If one gets hacked, you would not lose the others.

Wondering how come somebody knows you have certain accounts ?

Simply by probing them… After all, all people you know have a Facebook account, LinkedIn and so on… This is why it is better to enable two-factor authentication for online services that support this.

I wrote a lot about how to create good passwords and how to remember them as well as how to enable two-factor authentication.
