Password Security Best Practices
Use Unique Passwords
Never reuse passwords across accounts. One breach can compromise all accounts sharing the same password.
Longer is Stronger
A 16-character password is exponentially harder to crack than an 8-character one. Aim for 16+ characters.
Use a Password Manager
Store your unique passwords securely in a password manager like Bitwarden, 1Password, or LastPass.
Enable Two-Factor Auth
Even with strong passwords, enable 2FA on important accounts for an extra layer of security.
Avoid Personal Info
Never use birthdays, names, or common words. Hackers use these in dictionary attacks.
Change Compromised Passwords
If a service reports a breach, change that password immediately and any similar ones.
Understanding Password Strength
Password strength is measured by entropy - the number of possible combinations a password could have. More entropy means more guesses needed to crack it. A password's entropy depends on its length and the size of the character set used.
Weak: 8 characters, lowercase only
~208 billion combinations. Can be cracked in minutes with modern hardware.
Moderate: 12 characters, mixed case + numbers
~3 sextillion combinations. Would take years to crack with current technology.
Strong: 16 characters, all character types
~10 octillion combinations. Practically uncrackable with brute force.
Maximum: 20+ characters, all types
Astronomical combinations. Would outlast the universe to crack.
Each additional character multiplies the number of possible combinations. Adding symbols to your character set also dramatically increases entropy. That's why we recommend using all character types and at least 16 characters.
Frequently Asked Questions
How long should my password be?▼
For most accounts, a minimum of 12-16 characters is recommended. For high-security accounts like banking or email, use 20+ characters. Our generator supports up to 64 characters for maximum security.
Is this password generator secure?▼
Yes. All passwords are generated entirely in your browser using JavaScript. No passwords are stored, transmitted, or logged on any server. Your passwords never leave your device.
Why should I use a password generator?▼
Humans are bad at creating random passwords - we tend to use patterns, dictionary words, and personal information that hackers can guess. Password generators create truly random combinations that are much harder to crack.
Should I include special symbols in my password?▼
When possible, yes. Including symbols (!@#$%^&*) significantly increases password complexity. However, some systems don't allow special characters, so you can disable them if needed.
Can I use the same password for multiple accounts?▼
No, you should never reuse passwords. If one account is breached, all accounts with that password become vulnerable. Generate a unique password for each account and use a password manager to keep track of them.
What makes a password 'strong'?▼
A strong password is long (16+ characters), random (not based on words or patterns), and includes a mix of character types (uppercase, lowercase, numbers, symbols). It should be unique to each account.
