Password Generator for printed materials
Print is where password generation gets specific. The password needs to scan reliably from a few inches away, under uncontrolled lighting, possibly slightly crumpled or smudged.
Sizing rules
- Minimum size for scanning at arm's length: 2 cm × 2 cm (about 0.8 inches).
- For posters meant to be scanned from across a room: at least 10 cm × 10 cm, scaled up linearly with distance.
- Always include the quiet zone — the empty border. Without it, scanners struggle.
Print-specific tips
Generate at the largest size you'll need, then scale down in the layout — never up. PNG with high error-correction is the safest format for press output. Test with a real phone before you commit to the print run.
