Today, our security tip #18 in this Christmas calendar is to never share passwords or passphrases. You might have heard the term “sharing is caring”, but it doesn’t apply for passwords and passphrases at all. It is extremely important that you do not share any passwords or passphrases, which means that everyone needs to have their own logins to every system. Having a shared password will very quickly translate to catastrophe when an attacker has gained access to a system on your network.
Today, our security tip #12 for a secure Christmas is to don’t enter your username and password on any computer you don’t control. When using a computer that isn’t your own, make sure you don’t input any of your accounts or passwords. While the person whom the computer belongs to might not be out to take your password, you can’t be sure that this person hasn’t accidentally had malware installed on it.
Every year, malware and spam messages use to increase when it’s Christmas time. That’s why our security tip #3 is to use hard to guess passwords. There are a lot of things to consider in order making sure you have a password that is hard to guess. To create a hard to guess password, we recommend that your passwords should:
- be at least 8 characters long
- have special characters/symbols in it
- have a mix of upper- and lower-case.
You should also have different passwords on different sites, and change them often. This, while good, is quite hard to follow, which means that people most of the time pick easy passwords and tend to use the same password for many sites. In order to avoid this, it’s best to automate the password process, with an application that handles all of this for you. If you want to learn more, we have written a previous blog post about the importance of not reusing passwords. Microsoft has also written about this subject, and they have some tips as well as a password checker to see how secure your password is.
