Frankly, a lot of these look like a total pain, but you wanted to know…

- Strong passwords, kept safe. Passwords these days have to be ridiculously long to be safe against crackers. That includes the password to email accounts, and passwords to unlock devices, and passwords to web services. If it’s bad to re-use passwords, and bad to use short passwords, how can you remember them all? Use a password manager. Even write down your passwords and keeping them in your wallet is safer than re-using the same short memorable password — at least you’ll know when your wallet is stolen. You can create a memorable strong master password using a random word system like that described at diceware.com.
