Password security tips, guides, and best practices — updated for 2026.
How Long Should a Password Be?
September 25, 2026
Length is the single most important factor in password security. Learn the minimum lengths for every account type in 2026, backed by NIST guidelines and real cracking data.
What Makes a Password Strong?
September 25, 2026
Password strength comes from two things: length and randomness. Learn why clever substitutions fail, what entropy means in practice, and what actually protects your accounts.
Should You Use a Password Manager?
September 25, 2026
Most security experts recommend password managers. Learn why they are safer than alternatives, which types exist, what risks remain, and how to get started today.
Why You Should Never Reuse Passwords
September 25, 2026
Why reusing passwords is dangerous — how credential stuffing works, the scale of breached password databases, and the simple rule that protects you.
Two-Factor Authentication Explained
September 25, 2026
Two-factor authentication adds a second layer beyond your password. Learn how TOTP, SMS, hardware keys and passkeys work, and why some 2FA methods are safer than others.
What Is a Password?
September 25, 2026
A password is a secret string that proves your identity to a system. Learn how passwords work, why they were invented, how websites verify them without storing them, and what comes next.
How Websites Store Passwords
September 25, 2026
Learn how responsible websites store passwords using hashing, salting and bcrypt. Understand why some breaches expose passwords and others do not.
How Hackers Crack Passwords
September 25, 2026
Brute force, dictionary attacks, rainbow tables, credential stuffing, phishing — the five methods hackers use to crack passwords, and the complete defence against each.
Password Managers Explained
September 25, 2026
How password managers encrypt your vault with AES-256, why zero-knowledge architecture matters, what happened when LastPass was breached, and whether you need one.
Passkeys Explained
September 25, 2026
Passkeys use biometrics and cryptographic keys to log you in without a password, and are designed to resist phishing. Learn how they work, which sites support them, and whether you should switch now.
What Is Credential Stuffing
September 25, 2026
Credential stuffing tests billions of leaked passwords against your accounts automatically. Three steps make the attack irrelevant: unique passwords, MFA, and breach monitoring.
Brute Force vs Dictionary Attack
September 25, 2026
Brute force tries every possible combination. Dictionary attacks use wordlists of known passwords. Learn how each works, which is more effective, and what stops both.
Password Entropy Explained
September 25, 2026
Password entropy measures how unpredictable a password is in bits. Learn the formula, why human-chosen passwords have less entropy than they look, and what scores you actually need.
Passphrases vs Passwords
September 25, 2026
Passphrases are longer and more memorable. Random passwords are shorter for the same entropy. Learn the trade-offs, when to use each, and why randomness matters more than either.
Random vs Memorable Passwords
September 25, 2026
The trade-off between random and memorable passwords — when each approach is right, and the one exception that makes memorable passwords secure.
Password Length vs Complexity
September 25, 2026
