Passphrase Review

Spot obvious passphrase weak spots.
Waiting for input.

Passphrase Review is a private browser-side check for obvious weak spots before a secret is used, shared, or stored.

What it checks

  • Character length.
  • Character variety.
  • Repeated runs.
  • Phrase-like structure.
  • A rough estimated search-space signal.

Use cases

  • Sanity-check a phrase before it goes into a password manager.
  • Compare a memorable phrase against a shorter mixed-character secret.
  • Catch repeated patterns that are easy to miss by eye.
  • Review training examples without sending text to a remote scoring service.

Local privacy boundary

The passphrase stays in the browser. The site does not upload it, log it, send it to analytics, or compare it against remote breach databases.

Safer review workflow

Use the result as a heuristic, then store the final secret in the right password manager or credential vault. Do not paste real production secrets into unrelated websites just to get a score.

Limits

This is not a breach check, password-manager audit, or guarantee that a phrase is safe. It only flags visible patterns from the value you type.

Use Passphrase Generator when you need a new phrase, or Hash Inspector for local digest work.
