Open the original- What it measures
- An equal error rate is the point where the rate of wrongly rejected real users equals the rate of wrongly accepted impostors. Lower is better.
- What it does not show
- Measured on one fixed password in a lab. The result is a benchmark for comparing methods, not a measure of how well typing identifies people in daily life.
