+SilverBullet supports simple authentication for a single user.

-## Single User
 By simply passing the `--user` flag with a username:password combination, you enable authentication for a single user. For instance:
 
 ```shell

 Will let `pete` authenticate with password `1234`. 
 
-## Multiple users
-Although multi-user support is still rudimentary, it is possible to have multiple users authenticate. These users can be configured using a JSON authentication file that SB can generate for you. It is usually named `.auth.json`. 
-
-You can enable authentication as follows:
+Alternative, the same information can be passed in via the `SB_USER` environment variable, e.g. 
 
 ```shell
-silverbullet --auth /path/to/.auth.json
+SB_USER=pete:1234 silverbullet .
 ```
 
-To create and manage an `.auth.json` file, you can use the following commands:
-
-* `silverbullet user:add --auth /path/to/.auth.json [username]` to add a user
-* `silverbullet user:delete --auth /path/to/.auth.json [username]` to delete a user
-* `silverbullet user:passwd --auth /path/to/.auth.json [username]` to update a password
-
-If the `.auth.json` file does not yet exist, it will be created.
-
-When SB is run with a `--auth` flag, this fill will automatically be reloaded upon change.
-
-### Group management
-While this functionality is not yet used, users can also be added to groups which can be arbitrarily named. The `admin` group will likely have a special meaning down the line. 
-
-When adding a user, you can add one more `-G` or `--group` flags:
-
-```shell
-silverbullet user:add --auth /path/to/.auth.json -G admin pete
-```
-
-And you can update these groups later with `silverbullet user:chgrp`:
-
-```shell
-silverbullet user:chgrp --auth /path/to/.auth.json -G admin pete
-```
+This is especially convenient when deploying using Docker

+## Next
+* Removed built-in multi-user [[Authentication]], `SB_AUTH` is no longer supported, use `--user` or `SB_USER` instead, or an authentication layer such as [[Authelia]]
+* Technical refactoring in preparation of multi-tenant deployment support (allowing you to run a single SB instance and serve multiple spaces and users at the same time)
+  * Lazy everything: plugs are now lazily loaded (after a first load,  manifests are cached). On the server side, a whole lot of infrastructure is now only booted once the first HTTP request comes in

 ## 0.5.8
 * Various bugfixes, primarily related to the new way of running docker containers, which broke things for some people. Be sure to have a look at the new [[Install/Local$env|environment variable]] configuration options

This will disable the Online [[Client Modes]] altogether (and not even show the sync icon in the top bar). Conceptually, [silverbullet.md](https://silverbullet.md) runs in this mode.
