|
|
|
The authentication is tied to the auth [plugin](plugins.md) you are using. The package restrictions are also handled by the [Package Access](packages.md).
|
|
|
|
The client authentication is handled by the `npm` client itself. Once you log in to the application:
|
|
|
|
```bash
|
|
npm adduser --registry http://localhost:4873
|
|
```
|
|
|
|
A token is generated in the `npm` configuration file hosted in your user home folder. For more information about `.npmrc` read the [official documentation](https://docs.npmjs.com/files/npmrc).
|
|
|
|
```bash
|
|
cat .npmrc
|
|
registry=http://localhost:5555/
|
|
//localhost:5555/:_authToken="secretVerdaccioToken"
|
|
//registry.npmjs.org/:_authToken=secretNpmjsToken
|
|
```
|
|

|
#### Anonymous publish {#anonymous-publish}
|
|
|
|
`verdaccio` allows you to enable anonymous publish. To achieve that you will need to correctly set up your [packages access](packages.md).
|
|
|
|
Eg:
|
|
|
|
```yaml
|
|
'my-company-*':
|
|
access: $anonymous
|
|
publish: $anonymous
|
|
proxy: npmjs
|
|
```
|
|
|
|
As is described [on issue #212](https://github.com/verdaccio/verdaccio/issues/212#issuecomment-308578500) until `npm@5.3.0` and all minor releases **won't allow you publish without a token**.
|
|
|
|
## Understanding Groups {#understanding-groups}
|
|
|
|
### The meaning of `$all` and `$anonymous` {#the-meaning-of-all-and-anonymous}
|
|
|
|
As you know _Verdaccio_ uses `htpasswd` by default. That plugin does not implement the methods `allow_access`, `allow_publish` and `allow_unpublish`.
|
|
Thus, _Verdaccio_ will handle that in the following way:
|
|
|
|
- If you are not logged in (you are anonymous), `$all` and `$anonymous` means exactly the same.
|
|
- If you are logged in, `$anonymous` won't be part of your groups and `$all` will match any logged user. A new group `$authenticated` will be added to your group list.
|
|
|
|
Please note: `$all` **will match all users, whether logged in or not**.
|
|
|
|
**The previous behavior only applies to the default authentication plugin**. If you are using a custom plugin and such plugin implements
|
|
`allow_access`, `allow_publish` or `allow_unpublish`, the resolution of the access depends on the plugin itself. Verdaccio will only set the default groups.
|
|
|
|
Let's recap:
|
|
|
|
- **logged in**: `$all` and `$authenticated` + groups added by the plugin.
|
|
- **logged out (anonymous)**: `$all` and `$anonymous`.
|
|
|
|
## Default htpasswd {#default-htpasswd}
|
|
|
|
In order to simplify the setup, `verdaccio` uses a plugin based on `htpasswd`. Since version v3.0.x the `verdaccio-htpasswd` plugin
|
|
is used by default.
|
|
|
|
```yaml
|
|
auth:
|
|
htpasswd:
|
|
file: ./htpasswd
|
|
# Maximum amount of users allowed to register, defaults to "+inf".
|
|
# You can set this to -1 to disable registration.
|
|
# max_users: 1000
|
|
# Hash algorithm, possible options are: "bcrypt", "md5", "sha1", "crypt".
|
|
algorithm: bcrypt # by default is crypt, but is recommended use bcrypt for new installations
|
|
# Rounds number for "bcrypt", will be ignored for other algorithms.
|
|
rounds: 10
|
|
```
|
|
|
|
> The default algorithm is `crypt`, considered not secure for production environments, it's recommended for new installations use `bcrypt` instead. Note after verdaccio 6.x
|
|
> the default will be `bcrypt`.

| Property | Type | Required | Example | Support | Description |

|
| --------- | ------ | -------- | --------------------- | -------- | ---------------------------------------------------------------- |
|
|
| file | string | Yes | ./htpasswd | all | file that host the encrypted credentials |
|
|
| max_users | number | No | 1000 | all | set limit of users |

|
|
| rounds | number | No | 10 | >=5.13.0 | Rounds number for "bcrypt", will be ignored for other algorithms |
|
|
|
|
> In case you decide to prevent users from signing up themselves, you can set `max_users: -1`.
