No, I do not always use a secure password.
- On forums like these where there is absolutely no threat, no name, address or personal detail, I use a moderate password. A script kiddie will most likely not break it but someone who puts in effort will get past it. The worst that can happen is that I get baned because my account got hacked and abused, big deal, just re-register and start over.
- When testing out an installation in a VM I use a very weak password since there is a 0% threat
- On the home network, the boxes that are locked out and have no access to the wan, weak passwords, it is a secure home network after all.
I can however guarantee you that no one will be breaking into my desktop accounts (user and root) any time soon, also my router is as secure as it gets, same with the websites I maintain.
The places that matter get the whole shebang, otherwise I don't bother.
