Why Passphrases are Safer and Easier than Passwords . Let’s face it – passwords can be a pain. Complex and unique options are hard to remember, but reusing the same password across multiple accounts is even worse. The solution? Think less of random strings of characters and more of whole words or phrases. We all know why passwords are so important. According to Verizon, 83% of initial attack access is gained through stolen credentials. There are some obvious rules to protect yourself, such as the need to avoid ‘keyboard walks’ (like ‘qwerty’ or ‘12345’), a significant date, or even a favorite sports team or loved one’s name. These are major red flags because they’re relatively easy to guess. So, is making passwords more complex the answer? Hard to remember You might think strength lies in a seemingly random collection of letters (some of them capitalized), numbers, and special characters. The problem is that such passwords aren’t as random as you might think. User behavior is driving a convergence in passwords, rather than a divergence: they’re becoming more similar, thanks to the same old patterns cropping up repeatedly. Why does this happen? Because these complex passwords are difficult for people to remember, they’ve come up with ways to cope with security demands, often by defaulting to the same, familiar patterns. For example: According to this approach, the word ‘complicated’ could be rendered as ‘Complic@ted1!’. That might pass muster in most organizations, meeting default Active Directory password policies. However, attackers are very familiar with these strategies, which are easy for computer software to guess. Criminals use their knowledge to their advantage, optimizing their brute-force and hybrid dictionary attacks. Strength in length It’s easy to see why users could be tempted to use the same password for multiple accounts. Bitwarden found 68% of internet users manage passwords for over 10 websites – and 84% of these people admit to password reuse. This greatly increases the likelihood of a password becoming compromised.  One simple way to strengthen all the passwords in your active directory is to make them longer, rendering them harder to crack through brute force and hybrid dictionary attacks. This can be effective – in many ways, the longer the password, the stronger the password. However, we’re once more faced with the complexity problem. Long strings of random characters are very difficult for end users to remember, potentially putting us back to square one. The solution is to design long passwords that you’ll actually remember. That’s where passphrases come in. Let’s look at an example: below we have two potential passwords, one just eight characters in length, the other almost three times bigger, at 21 characters. Fridge-Elephant-Phone  84”fhg#l  Isn’t the second password more secure because it’s more complex? Not necessarily. The first example has length on its side. Perhaps more importantly, which of the two are you actually going to remember? For most users, it’ll be the longer phrase. The US authorities have recognized the benefits of passphrases. The FBI points to guidance from the National Institute of Standards and Technology (NIST) advising that password length is more important than complexity. “Instead of using short complex passwords, use passphrases that combine multiple words and are longer than 15 characters … Strong passphrases can also help protect against personal data breaches,” notes the FBI. Top tips for a strong passphrase The move from passwords to passphrases may seem daunting, but some simple approaches can help. For instance, the UK’s National Cyber Security Centre recommends combining three random words, while the Canadian Centre for Cyber Security says a passphrase should be at least four words and 15 characters in length. Random word generators can be helpful, while you could even suggest that end users deliberately misspell one of the words – as long as it’s still memorable. Here are some tips for creating good passphrases: Improve security and user experience Part of the problem is the sheer inconvenience involved with developing secure passwords. That’s why Specops Password Policy is simple from an admin point of view: you can choose whether to support longer passphrases or simply retain more traditional passwords and decide how to present information to the end user. It’s also crucial to develop a smooth and straightforward user experience. The Specops Authentication Client offers dynamic feedback, including real-time insights to help users meet the new policy. You can also offer length-based ageing, which ‘rewards’ users by providing them with more time between resets when they choose a longer password.   If you’re interested in making the move from passwords to passphrases with minimal hassle, speak to an expert today to learn how Specops Password Policy could fit in with your organization.

Daily Brief Summary

MISCELLANEOUS // Why Switching From Passwords to Passphrases Enhances Security

Passphrases are becoming preferred over complex passwords due to easier memorability and equivalent security enhancements.

Verizon reports 83% of cyberattacks begin with stolen credentials, emphasizing the need for stronger authentication methods.

Traditional complex passwords, often based on predictable user behavior patterns, are vulnerable to brute-force and hybrid dictionary attacks.

A study by Bitwarden shows that 84% of users admit to reusing passwords across multiple platforms, increasing the risk of security breaches.

The National Institute of Standards and Technology (NIST) and the FBI advocate for passphrases that are longer than 15 characters as they offer better security against breaches.

UK’s National Cyber Security Centre and Canadian Centre for Cyber Security recommend passphrases consisting of at least three or four random words.

Specops Software offers solutions like Specops Password Policy and Authentication Client, which facilitate the transition to passphrase use while enhancing the user experience.

Transitioning to passphrases can simultaneously improve security and user convenience, reducing the frequency of password resets with longer phrase usage.
