Password Generator
Generate strong, secure passwords instantly in your browser
—Why Use a Random Password Generator?
A strong password is your first line of defense against unauthorized access. FileFlip's password generator uses the Web Crypto API — the same cryptographic standard used by browsers for HTTPS — to generate truly random passwords. Unlike predictable human-chosen passwords, cryptographically random passwords are virtually impossible to guess or brute-force. Your generated passwords are never sent to any server, logged, or stored anywhere. They exist only in your browser for the moment you need them.

Frequently asked questions
- Is this password generator truly random?
- Yes. FileFlip uses the Web Crypto API (crypto.getRandomValues), which is a cryptographically secure random number generator built into your browser. This is the same technology used by password managers and security tools. The randomness is not predictable or reproducible, making it safe for generating passwords for any account.
- Are my generated passwords stored anywhere?
- No. The entire password generation process happens in your browser using JavaScript. No data is sent to any server, no passwords are logged, and nothing is stored. Once you close the tab, the password is gone. This makes FileFlip one of the safest password generators available online.
- How long should a password be?
- Security experts recommend at least 12-16 characters for most accounts. For highly sensitive accounts like banking or email, use 20 or more characters. Longer passwords are exponentially harder to crack: a 16-character password with mixed characters would take billions of years to brute-force with current technology.
- Should I include symbols in my password?
- Yes, when the website allows it. Including symbols significantly increases password complexity. A 12-character password with letters and numbers has about 3.2 trillion combinations. Adding symbols increases this to over 20 trillion. However, some sites restrict which symbols are accepted, so adjust accordingly.
- What makes a password strong?
- A strong password combines length (16+ characters), variety (uppercase, lowercase, numbers, symbols), and unpredictability (no dictionary words, names, or patterns). The FileFlip strength indicator evaluates all these factors in real time to help you create a password that meets modern security standards.
- Can I use this to generate a PIN?
- Yes. Set the length to 4 or 6, enable only Numbers, and disable all other character sets. You will get a cryptographically random numeric PIN suitable for ATMs, phone lock screens, or any service requiring a numeric-only code.
- How often should I change my passwords?
- Current security guidance from NIST recommends changing passwords only when you suspect a breach, rather than on a fixed schedule. More important than frequency is uniqueness: use a different password for every account. A password manager can store them all securely so you only need to remember one master password.
- What is the difference between a password and a passphrase?
- A password is typically a random string of characters, while a passphrase is a sequence of random words (e.g. 'purple-elephant-river-42'). Both can be equally secure if long enough. Passphrases are easier to remember but harder to type on mobile. For maximum security with a password manager, use long random character passwords.
