# Import-CompromisedPasswords

## SYNOPSIS

Imports plain-text passwords into the compromised password store

## SYNTAX

```
Import-CompromisedPasswords [-Filename] <String> [[-BatchSize] <Int32>] [<CommonParameters>]
```

## DESCRIPTION

The Import-CompromisedPasswords cmdlet will import a file containing new line-separated plain-text passwords into the compromised password store.

## EXAMPLES

### Example 1

```powershell
PS C:\> Import-CompromisedPasswords -Filename "D:\password-protection\plain-text-passwords.txt"
```

Imports passwords from the file "D:\password-protection\plain-text-passwords.txt" into the compromised password store.

## PARAMETERS

### -BatchSize

Specifies how many passwords to read from the file before committing them to disk.

In order to minimize the impact of memory usage when importing passwords, the passwords are read from the file and committed to the store in batches of this size. The larger the batch size, the faster the import, but the more memory is used. If left unspecified, the default value of 5,000,000 is used which provides an adequate balance of memory usage and speed.

```yaml

## 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/advanced-help/powershell-reference/import-compromisedpasswords.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.
