Verdaccio is an plugabble aplication. Currently supports multiple plugins only for [Authentication](auth.md) but there are plans to [improve the plugin system](https://github.com/verdaccio/verdaccio/issues/169). If you are interested to develop your own plugin, read the [development](development.md) section.
`verdaccio` as a sinopia fork it has backward compability with plugins that are compatible with `sinopia@1.4.0`. In such case the installation is the same.
```
&> npm install --global sinopia-memory
```
### Configuration
Open the `config.yaml` file and update the `auth` section as follows:
The default configuration looks like this, due we use a build-in `htpasswd` plugin by default that you can disable just commenting out the following lines.
```yaml
htpasswd:
file: ./htpasswd
