# Two Factor Authentication

### What is two factor authentication?

Two Factor Authentication allows you to greatly increase the security of your AgileCase accounts. It links your account to an app on your smartphone which generates codes that expire after a short period.

When you go to log in to AgileCase, you will be prompted to enter the current code on the app as well as your password.

This boosts the security of your account as the two sources, you password and the code from your smartphone, are separated- if one is compromised then the other shall still prevent an intruder from accessing your account.

Currently, two factor authentication is free on AgileCase, but in the future it will become a premium feature with additional charges.

The lessons below show how to use two factor authentication apps on different kinds of smartphone:

* [iOS](/user-documentation/agilecase-security/two-factor-authentication/ios.md)
* [Android](/user-documentation/agilecase-security/two-factor-authentication/android.md)
* [Removing / Re-adding 2FA Settings](/user-documentation/agilecase-security/two-factor-authentication/removing-re-adding-2fa-settings.md)

Once you have two factor authentication enabled, an additional page will display after you enter you password to log in. This page will prompt you to enter the verification code from your smartphone app.

Once you have entered the code, you will be logged in to your account as normal.

## 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.agilecase.com/user-documentation/agilecase-security/two-factor-authentication.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.
