A brief history of the password — where it came from

How the password format was invented, what it's for, and why Password Generator matters. Browser-based, free, no signup, runs entirely on your device.

Generating a password sounds like it should require an app — and historically it did. Password Generator runs the same thing in your browser tab, with one tap and no signup.

Launch the tool: Password Generator — Free, no account required, no watermark.

A short history

The format Password Generator generates wasn't invented as marketing gimmickry. It was invented to solve a real industrial inventory-tracking problem, with constraints (scanning speed, damage resistance, error correction) that still shape its modern uses.

Knowing the history matters in one specific way: it explains why some options in Password Generator look the way they do. Error correction, redundancy levels, quiet zones — they're all design decisions inherited from the original use case, baked into the spec, kept because they still work.
