# User Security Log-in
From the user page, the Admin can define multiple access restrictions to enhance security.
user Log in Security
* **Lock Account:** When this checkbox is marked, the user cannot access the account. The admin can unlock the account at any time.
* **Force Change Password:** When cliked, **t**he user will receive a new link via email, prompting them to create a new password to access the Tenant. This is useful when the user has forgotten their password or when the Admin prefers to request a specific user to create a new login password.
* **Login Type:** The Admin can modify the login type by requesting the user to use:
1. **Normal:**Access the Tenant using a password.
2. **2FA (Two-Factor Authentication),** Access is allowed only through a third-party app that generates a code.
3. **2FA OPTIONAL,** The user can choose to use either 2FA or a password.
* **IP address:** The Admin can define specific IP addresses that are allowed to connect to the Tenant, excluding all others.

## 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.g-iot.io/platform-user-guide-book/administration/user/user-security-log-in.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.
