Password Security Guide
How to Create Strong Passwords — Complete Security Guide 2025
Most people use passwords that can be cracked in seconds. A weak password isn't just inconvenient — it puts your bank account, email, social media and identity at risk. This guide covers the science of strong passwords and how to use them without going insane.
What Makes a Password Strong?
Password strength is measured in entropy — the number of bits of randomness. Every additional bit of entropy doubles the number of combinations an attacker must try. The two factors that most determine entropy are length and character set size.
- Length 8, numbers only: ~26 bits — cracked in minutes on a GPU
- Length 12, mixed: ~71 bits — cracked in months
- Length 16, all types: ~100 bits — centuries on current hardware
- 5-word passphrase: ~65 bits — years, plus human-memorable
Password vs Passphrase — Which Is Better?
Passphrases (random word sequences like "correct-horse-battery-staple") are often better than random character passwords because they're both strong and memorable. A 4-word passphrase gives ~44 bits of entropy from a 7,776-word wordlist. A 6-word passphrase gives ~77 bits — equivalent to a 13-character random password.
Use passphrases for master passwords (password manager, email). Use random character passwords for everything else, stored in a password manager.
The One Password Rule
Never reuse passwords. When a website gets breached (and they do, regularly), attackers take the leaked passwords and try them on Gmail, banks and other services. This "credential stuffing" attack is the most common account takeover method. Use a unique, randomly generated password for every account.
