# Auth

After you have downloaded the latest release the first thing to do is to fill out the auth.json file. 

## Manual Method

Open auth.json in a text editor of your choice, the default windows notepad is sufficient enough, when you open auth.json for the first time you should see something like this:

Next, log into Onlyfans and press F12 to open the dev tools and select the 'Network' tab.

In the filter box type \`api\` and open any page on Onlyfans e.g Messages, you should see some requests appear in the list on the right within the Network tab:

Click on one of the requests you see in the list and scroll down until you find the 'Request Headers' section.

<figure><img src="/files/jH7qVhp60dZjttBLXB3z" alt=""><figcaption></figcaption></figure>

You should be able to find the 3 fields we need, `Cookie`, `User-Agent` and `x-bc`.

Within `Cookie` you will find 2 bits of information that we need to copy, these being `sess` and `auth_id`.

So heading back to your text editor:

The value of `USER_ID` will be set to what `auth_id` is set to.

The value of `USER_AGENT` will be set to what the `User-Agent` is set to in the Request Headers.

The value of `X_BC` will be set to what the `X-Bc` is set to in the Request Headers.

The value of `COOKIE` will be set to `auth_id=YOUR AUTH_ID HERE; sess=YOUR SESS HERE;`, please make sure you copy the values from within the `Cookie` field found in the Request Headers section.

If you have done everything correct you should end up with something like this (this is all dummy info):

```json
{
  "USER_ID": "123456",
  "USER_AGENT": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:121.0) Gecko/20100101 Firefox/121.0",
  "X_BC": "2a9b28a68e7c03a9f0d3b98c28d70e8105e1f1df",
  "COOKIE": "auth_id=123456; sess=k3s9tnzdc8vt2h47ljxpmwqy5r;"
}
```

## Browser Extension

You can also use this browser extension which you can add to Chrome and Firefox <https://github.com/whimsical-c4lic0/OF-DL-Auth-Helper/> to help get the required info instead of using the dev tools.

Finally you need to add the path to ffmpeg.exe which you should of downloaded earlier. I would recommend copying ffmpeg somewhere safe where you can then add the path to the `config.json` file. You can do this easily by holding `shift` when right clicking on the .exe file which should give you the option to `copy as path`, this will include `\` so you will need to replace them with `/`. In the config.json file the lines should look something like this `"`FFmpegPath`": "C:/ffmpeg.exe"`
