About Strong Password Generator

A genuinely random password is meaningfully more secure than one a person tries to invent, even a person deliberately trying to be unpredictable — human-generated “random” passwords tend to follow subtle, guessable patterns without the person realizing it, while a proper generator draws from your browser’s cryptographically secure random source.

Length matters more for security than complexity rules do — a longer password with fewer special-character requirements is often both stronger and more practical than a shorter one crammed with symbols purely to satisfy an arbitrary complexity rule.

This tool generates passwords entirely in your browser using a cryptographically secure random source, with no server involved and nothing transmitted anywhere — meaningful specifically because a password generator that did send data to a server would itself be a real security concern.

Frequently Asked Questions

How do I generate a strong password?

Set the length slider (6 to 64, default 16), tick the character types you want and click Generate. For important accounts choose at least 16 characters with all four types, copy the result straight into a password manager and use a different one for every account.

How do I create a strong password?

A strong password is long, random and used on only one account. Length matters more than clever substitutions. Random generation avoids predictable patterns people tend to pick, like names, dates and keyboard runs. Use this tool to create up to 20 at once.

Is this password generator safe to use?

Passwords are created in your browser using the browser's cryptographic random number generator, and the page does not send them anywhere. Still, copy the result into a password manager promptly and do not reuse it. It does not guarantee every selected type appears in each password.

How long should a generated password be?

This tool offers 6 to 64 characters. For most accounts 16 or more is a sensible choice, and longer is better for anything valuable. Very short passwords are easier to guess by brute force, so use short ones only where a site forces a limit.
