# Custom List

Sometimes you may need a custom list that requires a login identifier other than an email (eg, phone numbers, special usernames, etc). In such cases, you can simply rename the columns to the desired name and it will show up in the login form.

The second column in the csv is treated as the password field (regardless of what you reaname it to). If it is present the csv, we will authenticate all your users against the provided passwords. If you wish to skip password verification, remove this column from the csv.

A sample CSV containing some users with their names and an `arbitrary password` will look like:

A sample CSV containing some users with only their names and `no password` will look like:

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.gmetri.com/metaverse/publishing/authentication/custom-list.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
