# Test-IsCompromisedPassword

The `Test-IsCompromisedPassword` cmdlet checks to see if a specified string matches a value in the compromised password store.

## Syntax

```
Test-IsCompromisedPassword -Value <string> -Normalize

Test-IsCompromisedPassword -Hash <byte[]>

Test-IsCompromisedPassword -SecureString <SecureString> -Normalize
```

### Parameters

**`Value`**

Required. The string to test.

**`Normalize`**

Optional. If specified, [normalization rules](/password-protection/v1.0/help-and-support/normalization-rules.md) are applied to the password before being checked against the compromised password store. To test against the banned word store, use the [Test‐IsBannedWord](/password-protection/v1.0/advanced-help/powershell-reference/test-isbannedword.md) cmdlet instead.

**`Hash`**

Required. A binary hash to test.

**`SecureString`**

Required. The string to test as a SecureString.

### Return value

The cmdlet returns a boolean value indicating whether the input string or hash matches a value in the compromised password store.

### Examples

```powershell
# Add a password to the store
PS> Add-CompromisedPassword -Value password!!!

# Test the password and ensure it is found
PS> Test-IsCompromisedPassword -Value password!!!
True

# Prompt for a compromised password to test
PS> Test-IsCompromisedPassword -SecureString (Read-Host -Prompt "Enter the password to test" -AsSecureString)
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.lithnet.io/password-protection/v1.0/advanced-help/powershell-reference/test-iscompromisedpassword.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
