How to Create a Strong Password
Published: June 2026
Weak passwords are behind the majority of hacked accounts. The good news is that a strong password isn't complicated — it just needs to be long, random, and unique. This guide explains what actually makes a password secure, the mistakes to avoid, and how to generate one in seconds.
What makes a password strong
Three things matter, in order of importance:
- Length. This is the single biggest factor. Every extra character multiplies the number of guesses an attacker needs. Aim for at least 16 characters.
- Randomness. A password should not be a word, a name, a date, or a predictable pattern. Truly random characters are exponentially harder to crack.
- Uniqueness. Use a different password for every account. If one site is breached, attackers try the same password everywhere else.
How length beats complexity
A short password with symbols (like P@ss1!) is weaker than a long simple one. Here's roughly how long different passwords take to crack by brute force:
| Password | Length | Time to crack |
| Tiger12 | 7 | Instant |
| P@ssw0rd! | 9 | Hours |
| 16 random characters | 16 | Billions of years |
Length wins. A 16-character random password is effectively impossible to brute-force with current technology.

Common mistakes to avoid
- Personal info — names, birthdays, pet names, and addresses are easy to guess or find online
- Common substitutions — swapping "a" for "@" or "o" for "0" doesn't fool modern cracking tools
- Reusing passwords — one breach exposes every account using that password
- Keyboard patterns — "qwerty", "123456", and "asdfgh" are in every attacker's dictionary
- Short passwords with symbols — length matters far more than special characters
How to generate a strong password
- Open the password generator. Go to the password generator.
- Set the length. Choose at least 16 characters. Longer is always better.
- Include character types. Enable uppercase, lowercase, numbers, and symbols for maximum strength.
- Generate and copy. The tool uses your browser's cryptographically secure random number generator — the same standard used in encryption. Copy it straight into your password manager.
Privacy note: A good password generator creates passwords locally in your browser and never sends them anywhere. Our generator uses the Web Crypto API and transmits nothing — you can verify by generating one with the internet disconnected.
How to remember your passwords
You shouldn't try to memorise 16-character random strings for dozens of accounts. Instead:
- Use a password manager — it stores all your passwords securely and fills them in automatically. You only remember one master password.
- Make the master password a passphrase — four or five random words strung together (like "copper-violin-meadow-tractor") are long, strong, and memorable.
- Enable two-factor authentication — even if a password leaks, 2FA stops attackers from getting in.
