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
