Generated Passwords Resolve Two Issues
During the recent holidays, I decided to get around to that one project I’d been meaning to do: change all my passwords. I have 241 unique passwords, and even though my password manager at the time gave them strong scores, I just wasn’t happy with the whole situation. So, I dived into a project for the generations.
As you should expect, I’ve read all the security alerts and everything I could find out about layers of security at the websites I visit for personal matters and those I use to serve clients. Each site is different, and that includes the two-factor authentication steps. It should give you comfort to know that using website passwords can be as complex as nuclear-launch codes – though it’s not comforting to think that any code can be cracked.
Randomly generated passwords that are frequently changed offer the best protection against cracking, which is why nuclear-launch codes always change – and why codes for keyless-entry systems for homes, cars and garages are essentially one-time codes designed to thwart anyone with a code scanner who sits near your car or home. Some password managers can change random passwords automatically when a website requires. No matter which one you use, you’ll need to have a master password – and that’s the only password you’ll need to remember.
Changing all of your passwords is not a task for the faint-of-heart. You’ll need to have a password manager program, such as Dashlane, LastPass or 1Password, and you’ll need to pay attention to details. I happen to like Dashlane for two of its features: random password generation and its integration with all browsers and operating systems. I consider those features to be critical.
When you use a password manager to generate random passwords, you need to pay attention to the requirements of each website. Some websites require the use of symbols, but many of them restrict you to certain symbols. Some require upper- and lower-case letters, and some require numerals. Many websites specify a certain number of characters in a password, such as 8 to 12 or 12 to 16. Just be mindful of all requirements when you set up the random password generator for each website.
One of the steps I took – and something highly recommended for financial websites – was to create a randomly generated password, log in to the site to make sure it worked, and then change it almost immediately. Each randomly generated password should be impossible to remember because it should lack any kind of pattern. For example, there doesn’t appear to be anything meaningful to me in FdXKCX9ZKsw. When a website requires you to change the password, you should have a password manager that does this automatically. Dashlane and LastPass do this, but they handle the process differently.
If you want to change your password manager, you can download all of your passwords so that you can re-enter them in your new password manager.
You should also know that your master password resides locally on your computer or mobile device. If you change computers, phones or tablets, you’ll need to re-enter your master password manually, not all your passwords – and it’s probably a good idea to do so to protect your data.
There are two keys to making a password manager and randomly generated passwords work. One is to make sure that the password manager itself is the latest version available and that you install all updates. Remember, as we’ve said so many times before, updates almost always include security patches and bug fixes.
The other key is to have a strong master password – really a passphrase. An effective passphrase should be something long – 20 to 30 characters – that you can remember and that doesn’t contain any information about you that’s available in public records. It should include upper- and lower-case letters, at least one number and at least one special character. Even if you change it every two or three months, it’s the only one you need to remember.
We can help you evaluate password managers and help you with the installation process. We think passwords have to become extinct as other security measures take hold, but for now, passwords are deeply ingrained in our online lives. Call us – 973-433-6676 – or email us for password manager help.
