SO, MAKE IT EASIER FOR YOURSELF
Dropbox was the latest company to have email addresses and passwords exposed, but they won't be the last. Facing reality, you must come to terms with the fact that any Internet company or service will be hacked and it's not a question of "IF", but "WHEN" it will happen. Some preventative maintenance will save you from changing hundred's of passwords should one of your sites/services get hacked.
WHAT CAN YOU DO?
- If you don't already have a password manager that comes within security software you already have [i.e. - like Norton 360, or Symantec Internet Security] - then get one. This will allow you to make senseless/almost endless passwords like Cb!f1$4!hY&568zZ!432One! that aren't easy to guess/crack, AND...
- Make each password different for every website you visit that requires a password so when a website/service is hacked you only have to change one password instead of a "Buttload", along with...
- Create a backup of your password manager list with includes the website, login name and password, so should it be corrupted or otherwise unusable you can still retrieve your list.
In the "Vault" used by Norton 360 you can actually use it like your favorites and scroll down to the site you want to log into, click on it and the browser takes you to the website and logs you into it with your credentials.
When the vault is closed, you can access it, and most vaults have some sort of encryption used on the data held inside them. Every time you change a password you should make a new backup of the password manager/vault data to keep it as accurate and up-to-date as possible.
