The media is packed with articles about hackers that got access to pc’s because they had weak passwords. It seems these problems are huge, most people use Password[0-9] as their password. really smart people even use P@$$w0rd[0-9]:
- This article will explain how to choose a good password.
- I use Password Chameleon as my chrome “password manager” (the password is a hash of a website’s domain and a password. so every site gets a different hash, which makes it a very good solution IMO)
- Try to crack your own password to see if it’s weak. use john the ripper to do this: installation instructions, how to use, compiling error I had to deal with.
- Understand /etc/passwd and /etc/shadow.
