# How to create Local Run Manager credentials to perform a NextSeq 500/550 system check in NCS 4.0.X
An admin account for Local Run Manager (LRM) is required for users to use the NextSeq Service Software (NSS) to perform a system check. User management is required for LRM version 4 (NextSeq Control Software v4.2). However, on LRM version 2.X (NextSeq Control software 4.0.X), user management is optional.
On LRM version 2.X, users can create their own Local Run Manager (LRM) login credentials to enable user management in LRM. After creating the new LRM login, the user can use the new admin level account and log into the NSS to run the required system checks. This can be done through the following steps:
1. In LRM, navigate to **Tools** and then select **User Management**.\
2. Select **Enable**.
3. Create a new user with an Admin level account.
**Note**: a temporary password will be created and the user will be prompted to update the password. 
**Optional**: The user can disable **User Management** if desired.

## 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://knowledge.illumina.com/instrumentation/nextseq-500-550/instrumentation-nextseq-500-550-reference_material-list/000002088.md?ask=&goal=
```
`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.
