Secure random password generator

Create secure random passwords, passphrases, and PINs directly in your browser. Generated values are not uploaded, stored, or tracked, and the app uses the browser crypto API for secure random values.

What makes a password secure?

A secure password is long, random, and unique. Length increases the search space, randomness avoids predictable human patterns, and uniqueness protects your other accounts if one service is breached.

Unique password generator

Use this as a unique password generator for each account instead of reusing one memorable password. Every new password is created from fresh browser randomness, so one leaked password should not unlock your email, banking, work, or cloud accounts.

Recommended password length

For most accounts, 16 random characters is a practical minimum. For email, finance, administrator access, recovery accounts, and other high-value logins, a 20- to 24-character random password is a stronger default.

Cryptographically secure random values

The generator uses crypto.getRandomValues, the browser cryptography API, for random passwords, passphrases, and PINs. That makes it a cryptographically secure password generator, not a cryptocurrency wallet seed or recovery phrase tool.

Password vs passphrase

Choose a random password when a password manager can store it for you. Choose a random passphrase when you need a secret that is easier to type, such as a device login, master password, or encrypted archive password.

Popular password tools and guides

Is this secure random password generator private?

Yes. Passwords, passphrases, and PINs are generated locally in your browser and are not stored, sent, or tracked.

What makes a password secure and complex?

A secure password is long, random, unique to one account, and not based on names, dates, keyboard paths, or reused patterns.

What length should a random password be?

Use at least 16 characters for general accounts. A 20- to 24-character random password is a strong default for important accounts.

Does this create unique passwords?

Yes. Generate a different random password for every account so a breach on one service does not expose your other logins.

Should I use a password or a passphrase?

Use random passwords with a password manager and passphrases when you need something easier to type.
