- Cybersecurity advice has been the same for years - create better passwords to protect your security online. So why are passwords like 'qwerty' still so common?
- The onus should be put on websites and services to encourage and enforce better “cyber hygiene”, writes a professor of cybersecurity.
- Websites should at least have processes in place to filter out poor passwords – a “blacklist” of common choices.
Year after year, passwords like “123456”, “qwerty” and even “password” are found to be the most popular choices and 2021 was no exception.
These reports generally come with the same advice to users: create better passwords to protect your security online. Although this is may well be true, it’s also time to realise that years of promoting this message has had little or no effect.
To improve things, I believe we need to stop blaming people and instead put the onus on websites and services to encourage and enforce better “cyber hygiene”.
Of course, it’s easy to point the finger at the users – they’re ultimately the ones making the poor password choices. But at the same time, it’s now well known that people commonly make these choices. So it’s fair to assume that without guidance or restrictions to prevent weak passwords, they’re likely to continue with the same habits.
Have you read?
Nonetheless, we have successive generations of users who are not told what a good password looks like, nor prevented from making lazy choices. It’s not hard to find examples of websites that will accept the very worst passwords without complaint. It’s similarly easy to find sites that require users to create passwords – yet give them no guidance in doing so. Or sites that will offer feedback that a user’s password choice is weak, but allow it anyway.
How providers can do better
If you’re responsible for running a website or a service that will accept the likes of “123456”, “qwerty” or “password”, it’s time to rethink your system. If you let users get away with bad choices, they will believe that they are acceptable and continue this bad practice.
On the contrary, by implementing stronger protocols, you can help to address the problem at its source. Websites should have processes in place to filter out poor passwords – a “blacklist” of common choices.
What is the World Economic Forum doing on cybersecurity
The World Economic Forum's Centre for Cybersecurity is leading the global response to address systemic cybersecurity challenges and improve digital trust. We are an independent and impartial global platform committed to fostering international dialogues and collaboration on cybersecurity in the public and private sectors. We bridge the gap between cybersecurity experts and decision makers at the highest levels to reinforce the importance of cybersecurity as a key strategic priority.
Our community has three key priorities:
Strengthening Global Cooperation - to increase global cooperation between public and private stakeholders to foster a collective response to cybercrime and address key security challenges posed by barriers to cooperation.
Understanding Future Networks and Technology - to identify cybersecurity challenges and opportunities posed by new technologies, and accelerate forward-looking solutions.
Building Cyber Resilience - to develop and amplify scalable solutions to accelerate the adoption of best practices and increase cyber resilience.
Initiatives include building a partnership to address the global cyber enforcement gap through improving the efficiency and effectiveness of public-private collaboration in cybercrime investigations; equipping business decision makers and cybersecurity leaders with the tools necessary to govern cyber risks, protect business assets and investments from the impact of cyber-attacks; and enhancing cyber resilience across key industry sectors such as electricity, aviation and oil & gas. We also promote mission aligned initiatives championed by our partner organizations.
The Forum is also a signatory of the Paris Call for Trust and Security in Cyberspace which aims to ensure digital peace and security which encourages signatories to protect individuals and infrastructure, to protect intellectual property, to cooperate in defense, and refrain from doing harm.

And while it can be useful to offer guidance for users at the point of password creation, sites should stop insisting on things that authoritative organisations like the UK National Cyber Security Centre and the US National Institute of Standards and Technology now say ought not to be enforced. For example, they advise against the requirement for password complexity (like including upper and lower case letters, numbers and punctuation symbols).
Both organisations indicate that increasing password length is more important than complexity. This is because longer passwords are more resistant to brute force cracking (where attackers try all letter, number and symbol combinations to find a match) and less complex passwords can be easier to remember.
Yet many sites continue to demand complexity and impose upper limits on length, in the process often blocking perfectly reasonable password choices that our browsers and other tools can automatically generate for us.
You may wonder why this is important. If people want to choose weak passwords and put themselves at risk, then why should that become the provider’s problem? One argument is that if a service is charged with protecting users’ personal data (as providers are through GDPR) then it doesn’t make a lot of sense to allow users to leave themselves vulnerable by choosing weak passwords.
It’s also worth noting that in some cases one user’s weak password could give an attacker a foothold into the system from which to exploit other weaknesses and increase their access. So it’s arguably in the provider’s interest to minimise these opportunities and protect other people’s data in the process.
Passwords aren’t going anywhere
We’re now seeing a move towards passwordless authentication, but this name in itself emphasises the dominance of password-based methods. Their death was predicted more than 15 years ago, and yet they’re still here. It’s safe to assume they’re going to be with us for some time yet.
So we have a choice: take collective responsibility to get the basics right – which involves action by users and providers – or maintain the collective effort to shrug our shoulders and complain about users’ behaviour.
For those providing and operating password-based systems, sites and services, the call to action is hopefully clear: check what your site permits and see if it should do better. If it lets weak passwords pass, then either change this, or at a minimum do something that tries to deter users from choosing them.
If you are reading this as a user and you’re looking for some good advice on creating better passwords, the UK National Cyber Security Centre provides some useful tips. These include combining three random words to give yourself longer but more memorable passwords, and saving your passwords securely in your browser to further reduce the burden of remembering passwords across multiple sites. So even if providers are not doing enough, there are still some things you can do to protect yourself.
