For the vast majority of us passwords are they only security mechanism that protects our email, our money or our healthcare information. This is why passwords and human behaviour are often the weakest link in network security.

If this password is weak it can be trivial for even a slightly motivated attacker to run an automated dictionary attack to try and compromise your password. For many passwords this can literally take seconds to do, simply because the passwords used are common everyday words.

The most common passwords used in 2015 are:

1. qwerty
2. 123456
3. qwertyuiop
4. 123456789
5. password
6. 12345678
7. 12345
8. 111111
9. 1qaz2wsx
10. qwe123

If you recognise something here you have a problem and you MUST change your password immediately. Rather than bore you with a long winded spiel, we suggest you invest a couple of minutes and watch this YouTube video:

If you don’t believe it is possible, look at how easy it is in this YouTube video:
