Estimate strength using length, character classes and pattern checks.

Inputs and results

Input: A password typed locally.

Output: Strength, rough entropy/crack-time estimate and suggestions.

How it works

1

A password typed locally.

2

Inspect the heuristic checks as you type.

Examples

science Example to try

Compare a repeated word with a longer random value.

Limitations

A heuristic, not a breach lookup or measured resistance. Crack times assume a model and can mislead for predictable or reused secrets.
