# Setting Up Two-Factor Authentication
PlexTrac enables two-factor authentication at the account level and is managed on the **Two-Factor Authentication** tab of the **Personal Settings** page. Two-factor authentication is a security measure that requires users to provide two forms of identification to access an account or system.
Two-factor authentication (2FA) is a security measure that significantly protects against unauthorized access to sensitive information and accounts. It works by adding an extra layer of verification to the traditional password or PIN login process. When users log in, they must provide their regular credentials, such as a username and password, and a second form of authentication.
The second authentication factor can take various forms, such as a unique code sent to the user's mobile device via SMS or generated by an authentication app, a fingerprint or facial recognition scan, a hardware token, or even a one-time password sent to an email address. The significance of 2FA lies in its ability to counteract the vulnerabilities of using passwords alone.
### Setting up Two-Factor Authentication

## 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.plextrac.com/plextrac-documentation/product-documentation-1/account-management/profile-personal-settings/setting-up-two-factor-authentication.md?ask=&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.
