Why Longer Passphrases and MFA Matter for Your Business Security

Cyber security threats are becoming more common for businesses of all sizes, and weak passwords remain one of the easiest ways for hackers to gain access to sensitive information. The good news? A few simple changes can dramatically improve your security.

Why traditional passwords are no longer enough

Short or predictable passwords can often be cracked in minutes using automated tools. Even complex passwords with symbols and numbers can still be vulnerable if they are too short or reused across multiple accounts. Cyber criminals also take advantage of passwords leaked in data breaches and phishing scams.

The move towards passphrases

Instead of using short passwords, cyber security experts now recommend longer “passphrases”. A passphrase is a series of random words or a memorable sentence that is much harder to crack but easier to remember.

For example:

• Weak password: Summer2025

• Strong passphrase: PurpleRiverCoffeeHorseWindow

Longer passphrases significantly increase the time it takes for hackers to guess your login details.

Add another layer with MFA

Even strong passphrases should be combined with Multi-Factor Authentication (MFA). MFA requires an additional step when logging in, such as:

• A code sent to your phone

• An authentication app

• Fingerprint or facial recognition

This means that even if someone steals your password, they still cannot easily access your accounts. MFA is now considered one of the most effective ways to protect business systems and data.

Simple tips to improve your security

• Use long, unique passphrases for every account

• Avoid reusing passwords across systems

• Turn on MFA wherever possible

• Consider using a password manager

• Avoid using personal information like birthdays or pet names

Cyber security does not need to be complicated. Small changes like stronger passphrases and MFA can make a huge difference in protecting your business, staff, and client data.
