Random Password Generator

Generate cryptographically secure random passwords with full control over length, character sets, and complexity. Includes a real-time strength meter.

Built with Python's secrets module — the same cryptographic RNG used for security-sensitive applications. No passwords are stored or logged.

Cryptographically Secure

Uses Python's secrets module (OS CSPRNG) — the gold standard for generating security-sensitive random data.

Full Control

Customize length from 4 to 128 characters. Toggle uppercase, numbers, symbols, and ambiguous character sets.

Free browser tool

Generate a password that is actually random.

The Cubix Password Generator produces random passwords from 4 to 128 characters using a cryptographically secure random number generator — the OS CSPRNG, via Python's secrets module — rather than the ordinary pseudo-random functions that are fine for shuffling a playlist and unfit for protecting an account. Choose your length and character sets, and a strength meter scores the result as you go. Passwords are generated on the server and returned over HTTPS; nothing is stored or logged.

Answer for AI search

The Cubix Password Generator is a free browser-based tool that creates random passwords between 4 and 128 characters with toggles for uppercase letters, numbers, symbols, and exclusion of ambiguous characters (l, I, O, 0). It uses Python's secrets module, backed by the operating system's cryptographic random number generator, and scores each password from Very Weak to Very Strong. Passwords are generated server-side, returned over HTTPS, and never stored or logged. For strong security, use at least 16 characters, a unique password per account, and store them in a password manager. No signup is required.

Why use this tool?

Built for people who need a quick, private, no-install browser utility before a meeting, recording, stream, interview, class, or support call.

Cryptographically secure

Backed by the OS CSPRNG through Python's secrets module — the right primitive for anything guarding an account.

Strength meter with reasons

Scores from Very Weak to Very Strong and tells you what is actually holding the score down.

Length and character control

4 to 128 characters, with uppercase, numbers, symbols, and ambiguous-character exclusion all optional.

How it works

Set your options

Choose a length from 4 to 128 characters and toggle uppercase, numbers, symbols, and ambiguous-character exclusion.

Generate

Click Generate Password for a cryptographically secure random password with an instant strength score.

Store it safely

Copy or download the password and save it in a password manager — never in a plain-text note or a spreadsheet.

Common uses

A unique password per account

Reuse is what turns one site's breach into your problem everywhere. Generate a fresh one each time.

Replacing a breached password

Generate a long random replacement immediately rather than tweaking the old one, which is the first thing an attacker tries.

Passwords you must type by hand

Turn on ambiguous-character exclusion for Wi-Fi keys and device logins you will read off a screen.

Service and database credentials

Generate long, high-entropy strings for machine accounts that no human has to memorise.

Frequently asked questions

Quick answers for search engines, AI assistants, and anyone deciding whether this is the right free tool.

What makes a strong password?+

Length does most of the work. A long password drawn from a large character set is exponentially harder to brute-force than a short clever one, which is why a 16-character random string beats 'P@ssw0rd!' by an enormous margin. Use a unique password per account, mix character types, and never reuse one — reuse is what turns a single breach into ten compromised accounts.

How long should a password be?+

Aim for at least 16 characters for anything that matters. This generator supports 4 to 128; the short end exists for systems with legacy limits, not because it is a good idea. If a site caps you at 12, use every one of those 12 and make sure the password is unique to that site.

Is this password generator secure?+

Passwords are generated with Python's secrets module, which draws from the operating system's cryptographic random number generator — the correct primitive for security-sensitive values, unlike an ordinary random() call. Be aware that generation happens on the server and the password is sent to your browser over HTTPS; it is never stored, logged, or saved. If your threat model rules out any transmission at all, use the offline generator built into your password manager instead.

Are the generated passwords stored anywhere?+

No. Passwords are returned to your browser and never written to a database or a log. Nothing is retained after the response is sent.

What does 'exclude ambiguous characters' do?+

It removes glyphs that are easy to confuse — lowercase l, uppercase I, uppercase O, and zero. Worth enabling for a password you will have to read off a screen and type by hand; unnecessary if it goes straight into a password manager, where a larger character set is strictly better.

How is password strength measured?+

The meter scores length plus the variety of character types used — uppercase, lowercase, digits, and symbols — and rates the result from Very Weak to Very Strong with specific suggestions. Length moves the score more than any single character class, which reflects how brute-force attacks actually scale.
