How to Generate a Strong Password
Weak passwords are the number one cause of account breaches. A truly random password is practically impossible to guess or crack by brute force. This guide shows you how to generate secure passwords instantly in your browser.
When You Need a Password Generator
- Creating a new account and need a unique, strong password
- Rotating passwords for security compliance
- Generating API keys or tokens for development
- Creating test credentials for staging environments
- Setting up passwords for shared team accounts
How to Generate a Password
Step 1: Open the tool
Go to the Password Generator. A password is generated automatically with default settings (16 characters, all character types).
Step 2: Customize settings
Adjust the length (4-128 characters) and toggle character types: uppercase, lowercase, numbers, and symbols. The strength meter updates in real time.
Step 3: Copy your password
Click "Copy" to copy the password to your clipboard. Use "Regenerate" if you want a different one. You can also generate multiple passwords at once.
What Makes a Password Strong?
Length matters most
A 16-character password with all character types has about 105 bits of entropy. A 8-character password has about 52 bits. Each additional character roughly doubles the time needed to crack it.
Randomness is key
Human-chosen passwords follow patterns (dictionary words, dates, keyboard sequences). A cryptographically random password has no patterns, making it resistant to both dictionary attacks and brute-force attacks.
Use a password manager
You don't need to memorize random passwords. Use a password manager (1Password, Bitwarden, etc.) to store them securely. Generate a unique password for every account.
Tips
- Use 16+ characters for important accounts (email, banking, cloud services).
- Never reuse passwords across accounts — if one is breached, all are compromised.
- If a site has symbol restrictions, increase length to compensate (20+ characters with letters and numbers is still very strong).
- Use the "Generate multiple" option to create passwords for several accounts at once.
FAQ
How long should my password be?
At least 12 characters for most accounts, 16+ for sensitive accounts (banking, email). Every additional character exponentially increases the number of possible combinations, making brute-force attacks impractical.
Are these passwords truly random?
Yes. The tool uses the WebCrypto API's crypto.getRandomValues(), which is a cryptographically secure pseudorandom number generator (CSPRNG). This is the same type of randomness used in TLS and other security protocols.
Should I include symbols in my password?
Yes, if the service allows it. Symbols dramatically increase the character pool (from ~62 to ~88 characters), which increases entropy. However, some older systems restrict which symbols are allowed — in that case, use a longer password with letters and numbers.
Is my password stored or sent anywhere?
No. Password generation happens entirely in your browser using JavaScript. No passwords are stored, logged, or transmitted. The tool has no backend.
