The biggest friction with most password tools is platform support. iPhone-only apps don't work on your Mac. Mac apps don't work on Windows. Chrome extensions don't work on Chromebooks (well, only Chrome extensions). Linux users get nothing. A browser-based generator skips all of this — same URL, every device, no install.
Works on every device with a browser.
Open Passphrase Generator →| Platform | Browser | Notes |
|---|---|---|
| Mac | Safari | Native browser, fastest on Apple Silicon |
| Mac | Chrome / Firefox | If you already use them |
| iPhone | Safari | Default iOS browser |
| iPhone | Chrome | Same engine as Safari on iOS |
| iPad | Safari | Larger screen, easier to read passphrase |
| Windows | Edge | Default Windows browser |
| Windows | Chrome / Firefox | Most popular alternatives |
| Linux | Firefox | Default on most distros |
| Linux | Chromium / Brave | Open source alternatives |
| Chromebook | Chrome | Native browser |
| Android | Chrome | Default Android browser |
| Android | Firefox | Privacy-focused alternative |
The reason it works everywhere is simple: it's a single HTML page with vanilla JavaScript. No native code, no platform-specific binaries, no Chrome extension API, no iOS App Store distribution.
iOS Safari handles the generator natively. The interface adapts to small screens, the toggle buttons are tap-friendly, and the Copy button uses the iOS clipboard API.
To use it on iPhone:
The Add to Home Screen trick gives you a dedicated icon that opens the generator like an app. It's not a real app — it's a browser shortcut — but the user experience is essentially the same.
Many people generate passwords on their iPhone because that's where they're signing up for accounts. The default iOS "Strong Password" suggestion gives you a 20-character random string that's hard to type and impossible to remember. A 5-word passphrase is better for accounts you'll need to type on devices without your password manager.
On Mac, Safari is faster on Apple Silicon and uses less battery. Chrome has the advantage of syncing tabs across devices if you use it everywhere. Either works perfectly.
For Mac developers, there's no benefit to a desktop app for this — the browser version is faster to launch and easier to share with teammates.
Edge has been the default Windows browser since Windows 10. It's based on Chromium and runs the generator perfectly. Chrome works equally well. Firefox is the open-source alternative.
None of them need administrator privileges — you can use the generator on a locked-down corporate Windows machine where you can't install apps.
Linux users tend to prefer browser-based tools because installing platform-specific apps on Linux often involves dependency chains. The generator is just a URL — no .deb, no .rpm, no flatpak, no snap.
It works on Ubuntu, Debian, Fedora, Arch, NixOS, Pop!_OS, Mint — every distro that runs a modern browser.
Chromebooks are browser-only by design, so they can't run desktop password generators at all. They CAN run Chrome extensions, but extensions have permissions you may not want. A pure browser-based generator works perfectly on Chromebook with no permissions needed.
Chromebook users in particular benefit from this approach because so many "free" generators are Chrome extensions that ask for "read every page you visit" permissions.
Same story as iPhone: Chrome and Firefox both work. The toggle buttons adapt to small screens and the Copy button uses the standard clipboard API.
For Android users who don't trust app stores or don't want yet another app, a browser-based generator is the cleanest option.
Almost nothing. The generator code is identical on every platform. The differences are:
None of these are blockers. The same passphrase you'd generate on Mac is the same one you'd generate on Android, with the same cryptographic randomness.
If you generate a passphrase on one device and need to type it on another, here are the quickest options:
