Frequently asked questions
Is this password generator truly random?
Yes. The tool uses the browser's built-in cryptographically secure random number generator (window.crypto.getRandomValues) — the same API used by banking and security applications. This is not pseudo-random. The output is statistically unpredictable and suitable for security-sensitive use.
Are my generated passwords stored or logged?
No. Everything runs in your browser. No password is ever sent to any server, logged, or stored anywhere. The password appears only in your browser and is gone as soon as you leave the page or generate a new one. Copy it immediately to your password manager.
How long should my password be?
At minimum 12 characters for personal accounts, 16 characters as a strong default, and 20+ characters for administrator or critical accounts. Password length is the single most important factor: each additional character multiplies the number of possible combinations by the character set size (typically 26–94). A 20-character random password is astronomically harder to brute-force than a 12-character one.
Should I include symbols in my password?
Yes, for maximum strength. Including uppercase, lowercase, numbers, and symbols maximizes the character set size, which multiplies the total possible combinations. However, some older systems do not accept certain symbols. If a site rejects your password, generate one without the specific symbol causing the error, or use a password without symbols but increase the length to compensate.
What is the difference between a password and a passphrase?
A password is a random string of characters. A passphrase is a sequence of random words (like "correct-horse-battery-staple"). Passphrases are easier to remember and can be very strong if they are long (4+ random words). For accounts you type manually and need to remember, a passphrase may be preferable. For accounts managed by a password manager, a random character password is typically stronger per character.
Can I use this for WiFi passwords?
Yes. A strong WiFi password using the WPA2 or WPA3 protocol can be up to 63 characters. Use a 20–30 character random password for your WiFi network. You only enter it once per device, so length is not a usability concern. Generate a QR code of the password using the WiFi QR Generator on this site so guests can connect by scanning instead of typing.
How do I remember a randomly generated password?
You should not try to memorize random passwords. Use a password manager (Bitwarden is free and open-source, 1Password is popular for families and teams). The password manager stores the password and autofills it on every device. You only need to remember one strong master password for the manager itself.
How often should I change my passwords?
Current NIST guidelines (the US government cybersecurity standard) recommend against mandatory periodic password changes unless there is evidence of compromise. Frequent password changes often lead to weaker, predictable passwords ("MyPassword1", "MyPassword2"). Instead, use strong unique passwords and change them only if a site is breached, you suspect unauthorized access, or you have shared the password.
Is it safe to generate passwords in a browser?
Yes, because the generation happens locally in your browser using the cryptographic APIs built into the browser itself. No password data is transmitted. The security risk to avoid is generating passwords on untrusted or shared computers, or using websites that claim to generate passwords but actually transmit them to a server — this tool does not.
What makes "password123" or "P@ssw0rd" weak?
These passwords appear complex but are among the first checked in dictionary and rule-based attacks. Security research consistently finds these in the top 100 most commonly used passwords. Attackers run specialized dictionaries containing millions of common passwords and their predictable variations (letter-to-number substitutions like a→@, e→3, o→0). A truly random password of equal length is exponentially more secure.
- Use a unique password for every account. Credential stuffing — using leaked username/password pairs to access other accounts — is the most common account takeover method. If one site is breached, unique passwords mean no other account is at risk.
- Use a password manager. Remembering 50+ unique 20-character passwords is impossible. Password managers (Bitwarden, 1Password, Dashlane) store and autofill all your passwords. You only need to remember one strong master password.
- Enable two-factor authentication (2FA). Even a weak password is significantly harder to exploit with 2FA enabled. Authenticator apps (Google Authenticator, Authy) are more secure than SMS-based 2FA.
- Change passwords after a breach. Check haveibeenpwned.com to see if your email has appeared in known data breaches. Change affected passwords immediately.
Password Security Best Practices
- 12 characters: The current minimum for most security guidelines. Takes years to crack with brute force using current hardware.
- 16 characters: Strongly recommended. Exponentially harder to crack than 12 characters. Suitable for all personal accounts.
- 20+ characters: Required for administrator accounts, root passwords, API keys, and anything protecting sensitive data or access to multiple systems.
- Uppercase + lowercase + numbers + symbols: A 16-character password using all four character types has approximately 6.7 × 10³⁰ possible combinations — beyond the reach of any current or near-future brute-force attack.
- No dictionary words. Passwords containing dictionary words are vulnerable to dictionary attacks even if they are long. Use random character strings, not substitutions like "p@ssw0rd".
Password strength comes down to two factors: length and character variety. Here is a practical breakdown:
