      description: "### Basic authentication scheme\n\nUse the HTTP Basic authentication scheme for InfluxDB `/api/v2` API operations that support it:\n\n### Syntax\n\n`Authorization: Basic BASE64_ENCODED_CREDENTIALS`\n\nTo construct the `BASE64_ENCODED_CREDENTIALS`, combine the username and\nthe password with a colon (`USERNAME:PASSWORD`), and then encode the\nresulting string in [base64](https://developer.mozilla.org/en-US/docs/Glossary/Base64).\nMany HTTP clients encode the credentials for you before sending the\nrequest.\n\n_**Warning**: Base64-encoding can easily be reversed to obtain the original\nusername and password. It is used to keep the data intact and does not provide\nsecurity. You should always use HTTPS when authenticating or sending a request with\nsensitive information._\n\n### Examples\n\nIn the examples, replace the following:\n\n- **`EMAIL_ADDRESS`**: InfluxDB Cloud username (the email address the user signed up with)\n- **`PASSWORD`**: InfluxDB Cloud [API token](https://docs.influxdata.com/influxdb/cloud/reference/glossary/#token)\n- **`INFLUX_URL`**: your InfluxDB Cloud URL\n\n#### Encode credentials with cURL\n\nThe following example shows how to use cURL to send an API request that uses Basic authentication.\nWith the `--user` option, cURL encodes the credentials and passes them\nin the `Authorization: Basic` header.\n\n```sh\ncurl --get \"INFLUX_URL/api/v2/signin\"\n    --user \"EMAIL_ADDRESS\":\"PASSWORD\"\n```\n\n#### Encode credentials with Flux\n\nThe Flux [`http.basicAuth()` function](https://docs.influxdata.com/flux/v0.x/stdlib/http/basicauth/) returns a Base64-encoded\nbasic authentication header using a specified username and password combination.\n\n#### Encode credentials with JavaScript\n\nThe following example shows how to use the JavaScript `btoa()` function\nto create a Base64-encoded string:\n\n```js\nbtoa('EMAIL_ADDRESS:PASSWORD')\n```\n\nThe output is the following:\n\n```js\n'VVNFUk5BTUU6UEFTU1dPUkQ='\n```\n\nOnce you have the Base64-encoded credentials, you can pass them in the\n`Authorization` header--for example:\n\n```sh\ncurl --get \"INFLUX_URL/api/v2/signin\"\n    --header \"Authorization: Basic VVNFUk5BTUU6UEFTU1dPUkQ=\"\n```\n\nTo learn more about HTTP authentication, see\n[Mozilla Developer Network (MDN) Web Docs, HTTP authentication](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication)._\n"
