How to use Password Generator
Generate strong, secure passwords instantly. Choose length, uppercase, numbers and symbols. Free online tool, no signup required.
When do you need a strong password?
Every online account needs a unique, strong password. Reusing passwords across sites is the single biggest security risk — a breach on one site exposes all your accounts using the same password.
Common scenarios:
- New account signup: Generate a unique password before registering so you never reuse an old one.
- Password rotation: Security best practice recommends changing passwords for sensitive accounts (email, banking) periodically.
- After a data breach: If a service you use reports a breach, generate a new password immediately. Check haveibeenpwned.com to see if your email appeared in known breaches.
- Admin and server passwords: System administrators use long random passwords for database credentials, SSH keys and API secrets.
- Wi-Fi passwords: Generate a strong WPA2 password for your home or office network.
What makes a password strong? Length matters most — a 16-character password with mixed types is exponentially harder to crack than an 8-character one. Include uppercase letters, lowercase letters, numbers and symbols. Avoid dictionary words, names or dates.
Frequently Asked Questions
How long should a password be?
At least 12 characters for personal accounts, 16+ for sensitive ones like email and banking. Each additional character multiplies the number of possible combinations exponentially. A 16-character random password would take millions of years to crack with current hardware.
Should I use a password manager?
Yes. A password manager (Bitwarden, 1Password, Dashlane) stores all your passwords encrypted behind one master password. You only need to remember one strong passphrase. This is the recommended approach for managing dozens of unique passwords.
Is it safe to generate passwords in a browser?
Yes — FlashUtils generates passwords entirely in your browser using the Web Crypto API. No password is ever sent to any server. You can verify this by disconnecting from the internet before generating.
What characters should I include?
For maximum strength, enable all character types: uppercase (A-Z), lowercase (a-z), numbers (0-9) and symbols (!@#$%). Some services restrict certain symbols — adjust accordingly. Never use only lowercase or only numbers.
What is the difference between a password and a passphrase?
A password is a random string of characters. A passphrase is a sequence of random words (e.g. 'correct-horse-battery-staple'). Passphrases are easier to remember and can be very strong — 4 random words give around 44 bits of entropy.
Random password vs passphrase vs PIN
A random character password (e.g. kX9#mP2$qL5@) offers maximum entropy per character — ideal for password managers where you never type it. A passphrase (e.g. purple-lamp-ocean-seven) is easier to type and remember while still being very strong. A PIN is weak by design — 4-6 digits offer very limited combinations. Use PINs only where required (phone lock screens, ATMs) and never for online accounts.
