## Authenticate your Cypress test runs in the following ways -

1. Set up the **environment variables**. (or)
2. Utilizing the **CLI params**. (or)
3. Mention your **username** and **access key** in the **lambdatest-config.json**.

## Utilizing CLI Params:

The following args can be used while running tests using the run command.

| Arg             | Shorthand  | Accepted values                      |
|------------------|------------|--------------------------------------|
| --username       | --user     | Your TestMu AI username              |
| --access_key     | --ak       | Your TestMu AI access key            |

For example -

```bash
lambdatest-cypress run --username=YOUR_LAMBDATEST_USERNAME --ak=YOUR_LAMBDATEST_ACCESS_KEY
```

## Using lambdatest-config.json:

The auth option will help you in specifying your username and access key. You can find your username and access key in the [TestMu AI Automation Dashboard](https://automation.lambdatest.com/build). Both, the auth credentials set in environment variables and the ones mentioned in the lambdatest-config.json file will get overridden.

The options supported in the auth are as follows:

| Arg          | Accepted values                      |
|--------------|--------------------------------------|
| **username** | Your TestMu AI username              |
| **access_key**| Your TestMu AI access key            |

For example -

```json
"lambdatest_auth": {
      "username": "<your username>",
      "access_key": "<your access key}"
   },
```

## Setup the Environment Variables:

While utilizing the CLI params, you can set up the following environment variables.

| Env variable          | Accepted values                      |
|-----------------------|--------------------------------------|
| **LT_USERNAME**       | Your TestMu AI username              |
| **LT_ACCESS_KEY**     | Your TestMu AI access key           |

Or you can also set environment variables using following commands:

- Linux / MacOS

```bash
export LT_USERNAME="YOUR_LAMBDATEST_USERNAME" \
export LT_ACCESS_KEY="YOUR_LAMBDATEST_ACCESS_KEY"
```

- Windows

```powershell
set LT_USERNAME="YOUR_LAMBDATEST_USERNAME" `
set LT_ACCESS_KEY="YOUR_LAMBDATEST_ACCESS_KEY"
```

Note

By doing so, the auth credentials you use in your **lambdatest-config.json** file will get overridden only if these options are not provided in **lambdatest-config.json** file.
