Password is a free password generator that creates strong, customizable passwords with a real-time strength meter. Choose length and character sets, avoid ambiguous characters, and generate as many passwords as you need — each one created locally in your browser and never transmitted anywhere.
The most common way accounts get compromised is not sophisticated hacking — it is weak, reused, or predictable passwords. Modern guidance favors long passphrases and randomly generated passwords over memorable ones, because length and entropy are what actually make a password hard to crack. Password lets you generate passwords with exactly the mix of characters you want, shows you the strength before you use it, and can exclude lookalike characters that cause manual-entry mistakes. Since generation happens locally in your browser, the passwords are never transmitted or logged anywhere.
According to security research, over 80% of data breaches involve compromised credentials. The most common attack vector is weak or reused passwords. When you use the same password across multiple sites, a breach on any one of them exposes all your accounts. Password generators solve this by creating unique, high-entropy passwords for each account.
Entropy measures how unpredictable a password is. A password with 80+ bits of entropy is considered very secure and would take billions of years to crack with current computing power. The strength meter in Password shows you the entropy of your generated password in real-time, so you can make informed decisions about your security.
Use unique passwords for every account. Never reuse passwords across different websites or services. If one site is breached, all accounts using that password become vulnerable. Password generators make it easy to create unique passwords for each account.
Make passwords long. Length is more important than complexity. A 20-character password with just lowercase letters is stronger than an 8-character password with all character types. Aim for 16-32 characters for most accounts, and 64+ characters for critical accounts like banking or email.
Use a password manager. Since you can't remember dozens of unique 20+ character passwords, use a password manager to store them securely. Popular options include Bitwarden (free and open-source), 1Password, and Apple Keychain. Generate passwords with Password, then save them in your password manager.
Enable two-factor authentication (2FA). Even the strongest password can be compromised. 2FA adds a second layer of security by requiring a code from your phone or hardware key in addition to your password. Enable 2FA on all accounts that support it, especially email and banking.
Password uses cryptographically strong random number generation (crypto.getRandomValues) to create passwords entirely in your browser. No passwords are ever transmitted, stored, or logged on any server. With options for uppercase, lowercase, numbers, symbols, and lengths up to 128 characters, you can create passwords that meet even the strictest security requirements.
A strong password is long (16+ characters), uses a mix of character types (uppercase, lowercase, numbers, symbols), and avoids predictable patterns. The Password strength meter evaluates your password in real-time using all these factors. Longer passwords with more character variety score higher on the entropy scale.
Yes, if you need to read or share the password verbally. The "Avoid ambiguous" option removes characters that look alike (like zero vs letter O, one vs lowercase L vs capital I) to prevent confusion. "Exclude similar" removes visually similar characters (like 8 vs B, S vs 5) to reduce reading errors.
Passwords are stored locally in your browser's localStorage only for your convenience — you can view your last 20 generated passwords. This data never leaves your device and can be cleared at any time using the "Clear" button. No passwords are sent to any server.
Password supports passwords from 4 to 128 characters. For most purposes, a password between 16 and 32 characters provides excellent security. For maximum security (like master passwords or encryption keys), use the full 128 characters.
Entropy measures how unpredictable a password is, measured in bits. A password with 80+ bits of entropy is considered very secure. For example, a 16-character password using all character types has about 105 bits of entropy. The strength meter shows your password's entropy so you can gauge its security.
For most accounts, 16-32 characters is ideal. For critical accounts like email, banking, or password manager master passwords, use 64+ characters. Remember: length matters more than complexity. A 20-character lowercase password is stronger than an 8-character password with all character types.
Yes! Password managers like Bitwarden (free, open-source), 1Password, or Apple Keychain let you store unique, strong passwords for every account without having to remember them. Generate passwords with Password, then save them in your password manager. This is the gold standard for password security.
Two-factor authentication (2FA) adds a second layer of security beyond your password. Even if someone steals your password, they can't access your account without the second factor (usually a code from your phone). Enable 2FA on all important accounts, especially email and banking.
Yes! Password works completely offline once the page has loaded. All password generation happens locally in your browser using the Web Crypto API. You don't need an internet connection to generate passwords, making it perfect for use in secure environments.
Ambiguous characters (0/O, 1/l/I) look similar and can cause errors when typing or sharing passwords verbally. The "Avoid ambiguous" option removes these confusing characters. This is especially useful when you need to read a password over the phone or write it down manually.
Password uses the Web Crypto API for cryptographically secure randomness, runs entirely in your browser, and includes features like ambiguous character exclusion, similarity filtering, and a real-time strength meter. Unlike many online generators, no data ever leaves your device.
