Popcorn Passwords is a free, browser-based tool that generates truly random passwords using the Web Crypto API — the same entropy source that powers SSL certificates and bank-level encryption. Choose anywhere from 8 to 110 characters, or switch to passphrase mode for memorable word-based passwords. No sign-up required. No data collected. Everything runs locally in your browser and is never transmitted to any server.
Most account breaches happen because of weak, reused, or guessed passwords. Not sophisticated hacking. A random 30-character password using uppercase, lowercase, numbers and symbols would take every computer on Earth billions of years to crack. A human-chosen password almost never comes close to that strength. Popcorn Passwords gets you there in one click.
Every character is selected using window.crypto.getRandomValues(), the same cryptographic entropy source used in SSL certificates and encryption keys. Each character has a perfectly equal probability of selection with no patterns, no bias, and no predictability. Your password is displayed, copied, and gone. Nothing is ever logged.
Use a unique password for every account. A truly random password with uppercase, lowercase, numbers, and symbols is impossible to memorise — a password manager is not optional, it is essential. Store every password in a reputable manager such as NordPass, Bitwarden, or 1Password. Enable two-factor authentication wherever possible. Never reuse a password across multiple sites because if one site is breached, every reused account becomes vulnerable.
This tool was born out of a love for 80s and 90s cult cinema. Every theme is a tribute to the aesthetics of the silver screen — from the neon glow of time-travelling DeLoreans to the gritty dials of fighter jets.

You will not remember a truly random password — and you should not try to. A password manager encrypts your vault, handles autofill, and means you never need to reuse or memorise a password again. Never store passwords in a text file, notes app, or your browser's built-in save. Enable two-factor authentication on every account that supports it.

PopcornPasswords generates every password entirely within your browser. No data is transmitted to any server. No passwords are logged, stored, or cached. We operate no database, no analytics pipeline, and no account system. Close this tab and your passwords are gone — permanently and by design.
We use Google Analytics to understand how many people visit the site and which features are popular. This collects anonymous usage data such as page views and general location. It does not track your passwords, your identity, or any personal information. We do not ask you to sign up, log in, or provide any personal details. You can block analytics by using an ad blocker or the Google Analytics opt-out extension.
Your chosen theme and display mode (dark, light, or office) are saved locally in your browser so they are remembered next time you visit. This uses your browser's built-in storage only. Nothing is sent to any server and no personal information is involved. You can clear this any time by clearing your browser data.

Most account breaches aren't sophisticated hacks — they're weak or reused passwords. A 30-character random password is billions of times harder to crack than an 8-character one. Use a unique password for every account.
A password using only lowercase is exponentially easier to crack. Mixing cases and numbers massively expands the search space — going from 26 possible characters per slot to 62. At 30 characters that's the difference between 26³⁰ and 62³⁰ combinations. That's not a small gap. That's the difference between a DeLorean doing 30 mph and 88 mph.
Symbols expand the pool to ~95 characters per slot. Every extra character type multiplies total combinations, not just adds to them. A 30-character password with symbols has more possible combinations than there are atoms in the observable universe. Even the Libyans couldn't crack that.
Every password is forged using the same class of ultimate cryptic formulae that power the most secure systems on the planet. Each character is selected through a process so unpredictable, not even Doc Brown could calculate the outcome in advance. The laws of probability are respected to the letter — every character gets a perfectly equal shot. No patterns. No shortcuts. Pure entropy, straight from the flux capacitor.
Characters like l, 1, 0, O, o, i, I, | look nearly identical depending on the font. If you ever need to type a password manually, tick this to strip them out. The password stays just as strong — the pool is only slightly smaller.
