Password lookup

Searching a password runs the question backwards. Instead of asking what was leaked about an account, it asks which accounts a known credential unlocks. This is how you size the blast radius of a reused password across every service it was ever used on.

What a result contains

Every account using it

All records that contain this exact value.

Addresses and usernames

The identities attached to each occurrence.

Reuse scope

How many separate services the credential reaches.

Age

When each exposure occurred, which shows whether reuse is historical or current.

How to read the result

  • This is the highest value search for anyone assessing their own exposure, because one result tells you how many places to change.
  • Do not test a credential against a service you do not own. Knowing where it is exposed is the finding, not the access.

Modules queried

  • Snusbase
  • LeakCheck
  • Community breach dumps
  • Combo lists

Each row in a result set names the module it came from, so findings stay traceable.
