Assuming that no one else has physical access to my computer, assuming that I don't run any unusual services, do I still need a strong password for my Ubuntu user account (it has admin privileges)?
I've heard that any Ubuntu system connected to the Internet needs a strong password because it may somehow affect not only this particular system, but even other machines with Internet access as well (for example, it would be easier to install spambots on a machine with a weak password). Is this true? How exactly does this happen? Do I also need strong passwords on my VirtualBox test systems?
Thank you
The reasons to have a strong password are multiple. You can use Google in this sense. I will only note that:
- Choosing a good password will help to keep your computer safe. If your password is easy to guess, someone may figure it out and gain access to your personal information.
- People could even use computers to systematically try to guess your password, so even one that would be difficult for a human to guess might be extremely easy for a computer program to crack.
Even so, Ubuntu does not force you to use a strong password. By default, Ubuntu requires a minimum password length of 6 characters, but, assuming that no one else has physical access to your computer and assuming that you don't run any unusual services, you can turn off all the password prompts or you can enable auto-login or you can set a short password on Ubuntu.
Regarding the second question, I can say that I find it aberrant. So no, you didn't heard well.
