Generate strong, secure passwords instantly. Nothing is sent to any server.
Password strength is arithmetic, not vibes. Every character drawn uniformly from a set of N possibilities adds log2(N) bits of entropy: a lowercase-only character contributes ~4.7 bits, adding uppercase, digits and symbols pushes each character to ~6.5 bits. A 16-character full-charset password carries ~104 bits — far beyond what any offline cracking rig can search. The entropy meter shows this math live as you adjust the options.
Passwords are generated with your browser's cryptographically secure random source (crypto.getRandomValues) — on your device, never on a server. A password that has crossed the network, even once, over any channel, is a password with a history. These have none: generate, copy, store in your manager, and it exists in exactly one place.
For anything a password manager fills automatically, maximum-entropy random strings win. For the handful of secrets you must type from memory — the manager's master password, your laptop login — a four-or-five-word passphrase ("correct horse battery staple" style) gets you 50–65 bits that a human can actually remember. Current NIST guidance (SP 800-63B) agrees: length beats forced complexity, and mandatory periodic rotation does more harm than good.
Provisioning accounts for a team, seeding test users, or generating API secrets? Bulk mode emits dozens at once, each independently random — no sequential patterns, no shared prefix.
