When it comes to securing our online accounts, we’re all familiar with the concept of passwords. Most of us have been creating them for years, usually settling for short combinations of letters, numbers, and maybe a special character if required. But as cybersecurity threats evolve, so do our options for protecting our digital lives. It’s time to consider an upgrade: the passphrase.
Passphrases are longer, more complex, and ultimately more secure alternatives to traditional passwords. Let’s explore how passphrases work, why they’re stronger, and how you can start using them to protect your accounts.
What’s the Difference Between a Password and a Passphrase?
A password is usually a single word or a short combination of characters that you use to log into your accounts. Although passwords can vary in complexity, many people opt for simple, easy-to-remember ones – which also makes them easier for hackers to guess or crack. Consider this: a typical 8-character password can be cracked in less than an hour using brute-force techniques.
In contrast, a passphrase containing 16 characters might take thousands of years to decipher.
This striking difference underscores the urgent need to shift from standard passwords to passphrases for improved security.
A passphrase, on the other hand, is generally much longer and consists of several words strung together. Think of a phrase or a short sentence like “CoffeeHikesSunsetsDogs.” Not only is it longer, but it also has a unique structure that makes it harder for automated tools to crack.
Here’s a quick comparison:
Password: Short, sometimes complex, but often reused and easily guessed (e.g., "P@ssw0rd!")
Passphrase: Longer, more complex due to the variety of words, and easier to remember because it’s a coherent phrase (e.g., “BlueSkyMorningRun!”)
Why Are Passphrases More Secure?
Length is a significant factor in security. A longer password or passphrase takes exponentially more time for an attacker to crack, especially if it contains unique, unrelated words. According to the Australian Cyber Security Centre (ACSC), passphrases can be highly effective at slowing down or stopping brute-force attacks, which rely on automated systems trying thousands of possible combinations per second.
Moreover, passphrases tend to be more memorable, which means you’re less likely to write them down or reuse the same passphrase across multiple accounts – two practices that weaken account security.
Tips for Creating Strong Passphrases
Building a strong passphrase doesn’t have to be difficult. Here are some tips from security experts:
Choose Unrelated Words: Avoid common phrases or sayings. Instead, combine unrelated words like “MountainsJazzPuzzleDesk.” This makes it more difficult for hackers to guess or use dictionary attacks.
Add Complexity Without Complication: You can introduce complexity by adding capital letters, numbers, or special characters. For instance, “Jazz4Puzzle#Mountains!”
Aim for Length: A passphrase should ideally be around 16 characters or more. The longer it is, the more difficult it becomes to crack.
Keep It Memorable: Think of things that are unique to you but don’t contain obvious personal information. For example, “RedSunsetFishingSaturday!”
By following these steps, you can create a passphrase that’s both secure and easy to remember, without relying on common phrases that attackers might guess.
Transitioning to Passphrases
Most websites today allow the use of passphrases, making it easy to boost your security. Start by changing the passphrases for your most important accounts—like email and banking. You will soon notice an improvement in your digital security.
It’s crucial to establish a habit of regularly updating your passphrases. Avoid predictable traits, like birthdays or pet names, as part of your passphrase. This proactive approach will help protect you from potential breaches.
