# HTTP Basic Authentication

HTTP Basic Authentication is a type of authentication where the client sends an `Authorization` header with a Base64 encoded username and password.

For some services,  the username or password might be blank.

PixieBrix has a generic integration definition `@pixies/integrations/auth-basic` for calling APIs that require HTTP Basic Authentication.

### Converting a cURL username command line option to PixieBrix

If you're coming from cURL, the username/password is what is provided to the `-u` or `--user` command line flag:

```
curl -u username:password
```
