How to Create a Strong Password You Can Actually Remember
What actually makes a password hard to crack, why length beats complexity, and how to check a password's real strength.
Most password advice focuses on complexity rules — one uppercase letter, one number, one symbol — but the single biggest factor in how long a password takes to crack is length, not the character mix. A long, random passphrase beats a short, "complex" password almost every time.
Why length matters more than complexity
Password cracking is a brute-force numbers game: every extra character multiplies the number of possible combinations an attacker has to try. An 8-character password with mixed case, numbers, and symbols can be cracked by modern hardware in hours; a 16-character passphrase, even using only lowercase words, can take centuries. Length wins.
How to generate a strong password
- Open the Password Generator.
- Set your desired length (16+ characters recommended) and choose which character types to include.
- Generate and use a fresh, unique password for each account — a password manager, not memory, should be how you keep track of them.
How to check a password you already use
- Open the Password Strength Checker.
- Enter the password to see its entropy and an estimated crack time.
- Treat "instant" or "minutes" crack-time estimates as a signal to change that password now, not eventually.
The one habit that matters most
Reusing a password across multiple sites means a breach on one unrelated site can compromise all of them. A password manager that generates and stores a unique password per site removes the need to memorize anything beyond one master password.
