Why use a strong password?

Using the same password over and over again across multiple sites might be convenient but it also introduces a huge security risk. Your email account, Facebook, Twitter, bank account, even your local grocery store, could be compromised if someone discovered your password. Choosing a unique and complex password for every online account helps ensure that your private information stays safe and secure.

What is a password strength tester and why should I use one?

A password strength tester gauges how long it might hypothetically take to crack your password by testing the password against a set of known criteria–such as length, randomness, and complexity.

Specifically, a strength tester measures how long it would take for someone else (or more commonly an automated computer program) to brute force an attack using every possible letter, number, and special character combination until they crack it. Having this information before you generate login credentials empowers you to choose the strongest possible password to keep your account information safe.

The key takeaway is password strength testers help you determine whether or not your passwords are strong enough to protect your online subscriptions, such as your bank account.

How do I strengthen my passwords?

  1. Make it unique: Use passwords unique to different online accounts. This reduces the likelihood that one compromised password would impact the security of your other accounts.
    DON’T use the same password for every account.
    DO use passwords unique to every account.
  2. Make it random: Ensure your passwords do not follow a recognizable pattern, and have a combination of uppercase and lowercase letters, numbers, special characters, or words unrelated to your personal information.
    DON’T use passwords with anything related to your personal information.
    DO use passwords with random combinations of uppercase and lowercase letters, numbers, special characters, and words unrelated to your personal information.
  3. Make it long: Using long passwords is critical to password strength. An 8-character password will take anywhere from a few minutes to a couple of hours to crack while a 16-character password will take a hacker a billion years to crack.
    DON’T use passwords with fewer than 14 characters.
    DO use long passwords consisting of 14 characters or more.

How do I manage unique passwords for every account?

To create strong and unique passwords for every website and account, a password manager makes it easy. This allows you to have unique, long, and random passwords for each site while only having to remember one master password. Bitwarden is a great option for a password manager as it offers a free and premium version, and included the ability to store unlimited passwords synced across unlimited devices and platforms.
