# Manage Note Permission

{%hackmd @codimd/docs-wide-styles %}

It is possible to change the access permission to a note through the little button on the top right of the view.
There are six possible options:

| Permission Icon/Name | Owner read/write | Signed-in read | Signed-in write | Guest read | Guest write |
|:------------------------------------------------------------------------------------ |:----------------:|:--------------:|:---------------:|:----------:|:-----------:|
| <span class="text-nowrap"><i class="fa fa-leaf fa-fw"></i> **Freely**</span> | ✔ | ✔ | ✔ | ✔ | ✔ |
| <span class="text-nowrap"><i class="fa fa-pencil fa-fw"></i> **Editable**</span> | ✔ | ✔ | ✔ | ✔ | ✖ |
| <span class="text-nowrap"><i class="fa fa-id-card fa-fw"></i> **Limited**</span> | ✔ | ✔ | ✔ | ✖ | ✖ |
| <span class="text-nowrap"><i class="fa fa-lock fa-fw"></i> **Locked**</span> | ✔ | ✔ | ✖ | ✔ | ✖ |
| <span class="text-nowrap"><i class="fa fa-umbrella fa-fw"></i> **Protected**</span> | ✔ | ✔ | ✖ | ✖ | ✖ |
| <span class="text-nowrap"><i class="fa fa-hand-stop-o fa-fw"></i> **Private**</span> | ✔ | ✖ | ✖ | ✖ | ✖ |

**Only the owner of the note can change the note's permissions.**

## Anonymous (Guest) related config

If you doesn't want guest user create note or view note, you can set `CMD_ALLOW_ANONYMOUS`, `CMD_ALLOW_ANONYMOUS_EDITS`, `CMD_ALLOW_ANONYMOUS_VIEWS` .
Set those config and the consequence is showing below table.

| `CMD_ALLOW_ANONYMOUS` | `CMD_ALLOW_ANONYMOUS_EDITS` | `CMD_ALLOW_ANONYMOUS_VIEWS` | `New guest note` button | `freely` permission | `editable/locked` permission |
| --------------------- | --------------------------- | --------------------------- | ----------------------- | ------------------- | ---------------------------- |
| true | - | - | active | active | active |
| false | - | false | inactive | inactive | inactive |
| false | false | true | inactive | inactive | active |
| false | true | true | inactive | active | active |

## Default Behavior

If you didn't change any config that related permission, the note permission is default to `editable`, And `CMD_ALLOW_ANONYMOUS` is set to `true`.

:warning: **Breaking Change** :warning:
After CodiMD 2.0.0, in order to prevent any user to create note, we change anonymous setting default value to:
- CMD_ALLOW_ANONYMOUS → `false`
- CMD_ALLOW_ANONYMOUS_EDITS → `true`
- CMD_ALLOW_ANONYMOUS_VIEWS → `true`
