About this utility
How to use Password & Passphrase Strength Estimator
Estimate offline guessing resistance, identify repeated/common patterns, and give local improvement guidance.
What to provide
The value stays only in component memory. Nothing is checked against an online breach database.
- Paste, type, or drag and drop a supported text file into the input area.
- Review the input and the clearly labeled output behavior.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
A conservative score, entropy estimate, pattern findings, and actionable guidance.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- This is an offline heuristic, not proof of resistance and not a breach lookup. Unique randomly generated passwords remain preferable.
