# What is Two Factor Authentication (2FA)
**Setting up Two-Factor Authentication**
Once logged in, click on the “Security” tab near the top left of the dashboard and you will see your account security page. From there, you can select your preferred 2FA method.
Alternatively, the first time you login (and until your 2FA is set up) you will immediately see the 2FA notification pop up. From there, you can select your preferred 2FA method and follow the simple steps to set up.
#### **Why Does CoinFLEX.US Require 2FA?**
We believe that passwords don’t provide the appropriate level of security required for companies that provide financial services, such as CoinFLEX.US.
Furthermore, many people use the same passwords. If your password were to be compromised by a malicious hacker, there is a risk that other online services you use may also be compromised.
#### **Disabling Your 2FA**
If you can login to your account, then you can disable it by yourself.
Step 1. After logging in to your account, select the “Security” tab, then click the “Security modification” button.
Step 2. Click “Turn off now >>” and enter your 2FA code. To turn it back on again, simply click the “Security modifications” button and enter your 2FA code.
#### **I Need Assistance Resetting my 2FA**
We can help you reset your 2FA registration if you require assistance. To do so, email our Customer Service team at using your CoinFLEX.US account registered email address and answer the following questions.
1. What is your currently registered 2FA method? If Authy, what phone number did you use?
1. If setting up Authy, what is your new phone number?
2. What is the reason for resetting your 2FA?
3. When did you register for a CoinFLEX.US account?
4. What is your currently available CoinFLEX.US balance?
5. When was the last time you logged in to your CoinFLEX.US account?

You will be required to take a selfie holding the ID document you used to set up your KYC as well as a note stating “CoinFLEX.US Reset 2FA” with your signature and today’s date.
Please keep your elbows close to your body when holding up the note and your ID document, and make sure your face, ID document, and note are clearly visible. If the selfie does not meet our standard you will be required to send a new email with a new selfie.

## 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://coinflex-us.gitbook.io/support/two-factor-verification/what-is-two-factor-authentication-2fa.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.
