Learn what makes a password strong, how to create one using best practices, and how to manage passwords safely without writing them down.
Step-by-Step Guide
Use at Least 12 Characters
Length is the single most important factor. A 12-character password takes billions of times longer to crack than an 8-character one. Aim for 16+ characters for accounts that hold financial or personal data. Length beats complexity every time.
Mix Character Types
Use all four character types: uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols (!, @, #, $, %, etc.). A strong password mixes all four: `Tr0ub4dor&3` is weak due to predictable substitutions; truly random mixing like `k#9mPqL!2vBx` is far stronger.
Avoid Predictable Patterns
Do not use dictionary words, names, birthdates, or keyboard patterns (qwerty, 123456). Do not substitute letters with obvious symbols (a→@, e→3, o→0) — attackers include these in dictionary attacks. Never reuse passwords across sites.
Use a Password Generator
The most reliable method: use a trusted password generator that creates cryptographically random strings. Our Password Generator lets you choose length and character types and generates a unique password instantly — no patterns, no predictability.
Store Passwords Safely
Never write passwords on paper or in plain text files. Use a reputable password manager (Bitwarden, 1Password, Dashlane) to store, autofill, and sync passwords securely. Enable two-factor authentication (2FA) on all important accounts as an extra layer.

Frequently Asked Questions
Q: How often should I change my passwords?
A: Current guidance (NIST 2024) recommends changing passwords only when there is reason to believe they have been compromised, not on a fixed schedule. Regular forced changes often lead to weaker passwords (e.g., "Password1!" → "Password2!"). Use a strong password and change it if there is a breach.
Q: Is a passphrase more secure than a random password?
A: A long passphrase (e.g., "correct-horse-battery-staple") can be very secure and is easier to remember. Four random common words at 5 characters each give about 50+ bits of entropy. However, for most online accounts, a password manager + random generated password is the strongest option.
Q: What is two-factor authentication and should I use it?
A: 2FA requires a second proof of identity beyond the password (e.g., a code from an app like Google Authenticator). Even if your password is stolen, 2FA prevents access. Always enable it on email, banking, and social media accounts.
