How to Generate a Strong Password (and Remember It)
Why Your Password Strategy Probably Needs an Upgrade
The average person reuses the same password across 8 different accounts. When one of those services suffers a data breach — and breaches happen every single day — every account sharing that password becomes compromised. This technique, called credential stuffing, is responsible for the majority of account takeovers.
A strong, unique password for every account is the single highest-impact security measure you can take.
What Makes a Password Strong?
Password strength is determined by entropy — the number of possible combinations an attacker must try to guess it. More combinations means more time, means safer.
The key factors:
- Length — This is the most important factor. Every additional character multiplies the search space exponentially. A 16-character password is not twice as hard to crack as an 8-character one — it is approximately 96 billion times harder (with a full ASCII character set).
- Character variety — Using lowercase, uppercase, numbers, and symbols expands the pool of possible characters at each position. A password using only lowercase letters has 26 options per character; adding uppercase, digits, and symbols can raise this to 94+.
- Randomness — Human-chosen passwords are not random. We gravitate toward familiar patterns, words, dates, and keyboard walks (like
qwertyor123456). Real randomness is critical.
Password Strength in Practice
| Password | Crack Time (modern GPU) | Verdict |
|---|---|---|
password | Instantly | Terrible |
P@ssw0rd! | Minutes | Bad (dictionary variant) |
Tr0ub4dor&3 | Days | Mediocre |
correct-horse-battery-staple | Centuries | Good (long passphrase) |
xK9#mQ2&vL7$nP4@ | Trillions of years | Excellent |

Password Generator →Passphrase vs. Random Password
A passphrase is a string of 4–6 random words: correct-horse-battery-staple. It is long (28+ characters), easy to type, and highly memorable. The entropy comes from the vast number of possible word combinations, not character complexity.
A random password like xK9#mQ2&vL7$nP4@ is shorter but denser in entropy per character. Both approaches are valid; the key is randomness and uniqueness per account.
The Only Realistic Strategy: A Password Manager
No human can remember 50 unique, random passwords. The solution is a password manager — a secure vault that stores all your passwords, encrypted with one master password. You only need to remember one thing; the manager remembers everything else.
Popular options: Bitwarden (free, open-source), 1Password, Dashlane, and KeePassXC (offline). All of them integrate with browsers and mobile devices to autofill credentials.
Additional Security Measures
- Two-factor authentication (2FA) — Even if your password is stolen, 2FA requires the attacker to also have your phone. Enable it everywhere it is available, especially email and financial accounts.
- Never reuse passwords — One breach should never cascade to other accounts.
- Check for breaches — Visit haveibeenpwned.com to see if your email addresses appear in known data breaches.
- Change compromised passwords immediately — If a service you use reports a breach, change that password (and any accounts sharing it) right away.
Conclusion
Strong passwords are long, random, and unique to each account. The practical way to achieve this at scale is a password manager combined with a strong, memorable master password. Start by generating a strong password for your most important account using our Password Generator, then work down your list from there.
