Password Best Practices

Everything you need to know about creating, managing, and protecting strong passwords — based on official UK National Cyber Security Centre guidance.

The Three Random Words Method

The UK's National Cyber Security Centre recommends a surprisingly simple approach to creating strong, memorable passwords: combine three random words. A password like CoffeeBridgeRocket is both long enough to be secure and easy enough to remember.

The key insight is that length beats complexity. A 20-character password made of three common words is far harder to crack than an 8-character password full of symbols — because the sheer number of possible combinations is astronomically larger.

Why this works

Three random words creates a password of ~18+ characters. At 10 billion guesses per second, it would take millions of years to crack by brute force. Make it even stronger by adding a number or symbol: CoffeeBridgeRocket7!

Important: make the words truly random

Don't pick words that relate to you (your pet's name, your city). Use a random word generator or open a dictionary to a random page. The randomness is what makes it strong.

Why You Need a Password Manager

The average person has over 100 online accounts. Remembering a unique, strong password for each one is impossible — which is why most people reuse passwords. This is one of the most dangerous habits in cybersecurity: if one site is breached, attackers try your password on every other site you use.

A password manager solves this completely. It generates and stores a unique, random password for every site. You only need to remember one master password. The NCSC explicitly recommends using a password manager as a core security practice.

Two-Factor Authentication (2FA)

Even a perfect password can be stolen through phishing or data breaches. Two-factor authentication (2FA) adds a second layer of security: even if someone has your password, they still can't log in without your second factor.

SMS 2FA (Avoid if possible)

Text message codes are better than nothing, but are vulnerable to SIM-swapping attacks where criminals convince your mobile carrier to transfer your number to their device.

Authenticator Apps (Recommended)

Apps like Google Authenticator, Authy, or Microsoft Authenticator generate time-based codes that are not vulnerable to SIM-swapping. Always prefer these over SMS.

Passkeys — The Future of Login

Passkeys are the next generation of authentication. Instead of a password, they use your device's biometrics (Face ID, fingerprint) to prove your identity. They are phishing-proof by design. Major platforms including Apple, Google, and Microsoft now support passkeys.

The 5 Most Dangerous Password Mistakes

1
Reusing passwords across sites
If one site is breached, attackers will try your credentials everywhere. Use a unique password for every account.
2
Using personal information
Birthdays, names of pets, children, or partners are the first things attackers try. Never use information that could be found on your social media.
3
Using common passwords
Passwords like 'Password1!' meet complexity requirements but appear in every hacker's dictionary. Length and randomness matter more than symbols.
4
Storing passwords in a browser without a master password
Browser-saved passwords are convenient but can be extracted by malware. A dedicated password manager with a strong master password is far safer.
5
Never changing compromised passwords
Check haveibeenpwned.com regularly. If your email appears in a breach, change the affected password immediately.
