Education: Learning about Strong Passwords and MFA

Cyber security measures like passwords and MFA are essential and should be one of the first security measures implemented in any IT system.

Within the education industry, it is often difficult to ensure security is at a strong level due to having a large system to protect with usually limited budget. However, it is critically important that these systems are secure due to the nature of the data stored within.

A successful cyber-attack could leave systems down for potentially weeks on end, having a massive impact on the ability for teachers to deliver lessons, while also affecting the reputation of the education body.

Although improvements have been made in recent years, sometimes the basics, like password management, can be overlooked.

Commonly used passwords

A good password is one that is complex and difficult to guess, with a combination of uppercase and lowercase letters, numbers, and special characters. Such passwords are harder for hackers to crack using brute force methods, which involve trying millions of combinations of characters until they find the right one. A good password can be the difference between a secure system and a compromised one.

One of the biggest risks of weak passwords is that they can be easily guessed by hackers. Common passwords like "123456," "password," and "qwerty" are easy to guess and are used by many people, making them a prime target for hackers.

It is vital that education bodies prioritize the use of strong passwords and implement strict password policies to ensure the security of their systems. But hackers don’t just create these password lists themselves, they harvest previously known passwords from other criminal’s data breaches. That’s why if a password of yours ends up in a data breach, then you must assume that everyone knows it and no longer use it.

The below graphic represents the time it would take for a cybercriminal to hack (brute force) a password using current technological capabilities.

Passwords should ideally be in the green section of this table, but if one of your current passwords is in another colour - do not worry. We would just advise that change it to something more secure and unique. With the rapid advancements in processing power, areas in the Orange section may look secure right now, but it the next couple of year, they may become much weaker.

The NCSC recommend use three random words followed by punctuation to create a secure and unique password. To find out more about passwords guidance, check out our Guidance | Eastern CRC (

Multi Factor Authentication

Two Factor Authentication (2FA) and Multi Factor Authentication (MFA) are incredibly useful in protecting your systems, accounts and devices.

2FA and MFA are essentially two or more methods that can verify your identity. A cybercriminal may be able to crack your username or password but they do not have your fingerprint, Face ID or your mobile phone to authorise a log in attempt on a mobile authenticator app.

2FA follows the idea of using a combination of two of ‘Something you know’, ‘Something you have’, and ‘Something you are’. So you might have a password that you have remembered, a physical identification token like a badge, and a fingerprint scanner. Often times the ‘something you have’ will take the form of a different device, like a mobile phone, in order to verify your identity when connecting to services online.

By enabling MFA across your systems, accounts, and devices you are providing a reliable defence against a cyberattack.

What else can I do?

Here are five other things that you can do now to improve your password security:

  1. See what passwords you and your staff have which have already appeared in data breaches and change them as soon as possible. Why not run a poll to see who has the most/least breaches? is a legit website where you can enter your email address and telephone number to see if your information has been captured in a data breach. You can also register your email address or domain and get notified if it appears in another breach.

  2. Have a clear password policy for staff and tell them why having strong, unique passwords are essential. If you need some help with this, our affordable student services offer security awareness training. Why not make a booking to discuss further?

  3. Enable 2FA and MFA wherever you can, but especially on your emails and social media accounts. Even with the best passwords, once someone knows that password then the system is no longer secure. With 2FA or MFA, even if the password and username are known, the criminal won’t have access to the second verification factor so they shouldn’t be able to just “log in”.

  4. If your staff have a lot of passwords to remember, consider getting an enterprise password manager so they only have to remember one and the password manager generates and remembers the rest – saying goodbye to reused passwords.

  5. Join the ECRC with free membership. Core members receive regular updates which include the latest guidance, news, and security updates as well as a series of "little steps" emails designed to get your business cyber resilient.
