# Configure a private registry for an organization scope with bun install

You can configure private registries in [`.npmrc`](/pm/npmrc) or [`bunfig.toml`](/runtime/bunfig#install-registry). Both work; we recommend `bunfig.toml` for its Bun-specific options.

To configure a registry for a particular npm scope:

```toml bunfig.toml icon="settings"
[install.scopes]
# as a string
"@myorg1" = "https://username:password@registry.myorg.com/"

# as an object with username/password
# you can reference environment variables
"@myorg2" = {
  username = "myusername",
  password = "$npm_pass",
  url = "https://registry.myorg.com/"
}

# as an object with token
"@myorg3" = { token = "$npm_token", url = "https://registry.myorg.com/" }

```

Your `bunfig.toml` can reference environment variables. `bun install` automatically loads environment variables from `.env.production.local`, `.env.local`, `.env.production`, and `.env`, regardless of `NODE_ENV`. It does not read `.env.development` or `.env.test`. See [Environment variables](/runtime/environment-variables).

```toml bunfig.toml icon="settings"
[install.scopes]
"@myorg3" = { token = "$npm_token", url = "https://registry.myorg.com/" }
```
