+# Protected paths **(CORE ONLY)**
+
+GitLab protects the following paths with Rack Attack by default:
+
+```
+'/users/password',
+'/users/sign_in',
+'/api/#{API::API.version}/session.json',
+'/api/#{API::API.version}/session',
+'/users',
+'/users/confirmation',
+'/unsubscribes/',
+'/import/github/personal_access_token'
+```
+
+GitLab responds with HTTP status code `429` to POST requests at protected paths
+that exceed 10 requests per minute per IP address.
+
+This header is included in responses to blocked requests:
+
+```
+Retry-After: 60
+```
+
+For example, the following are limited to a maximum 10 requests per minute:
+
+- User sign-in
+- User sign-up (if enabled)
+- User password reset
+
+After 10 requests, the client must wait 60 seconds before it can
+try again.
+
+## Configure using GitLab UI
+
+> Introduced in [GitLab 12.4](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/31246).
+
+Throttling of protected paths is enabled by default and can be disabled or
+customized on **Admin > Network > Protected Paths**, along with these options:
+
+- Maximum number of requests per period per user.
+- Rate limit period in seconds.
+- Paths to be protected.
+
+![protected-paths](img/protected_paths.png)
+
+Requests over the rate limit are logged into `auth.log`.
+
+## Migrate settings from GitLab 12.3 and earlier
+
+Omnibus GitLab protected paths throttle is deprecated and is scheduled for removal in
+GitLab 13.0. Please see the [GitLab issue](https://gitlab.com/gitlab-org/gitlab/issues/29952) and the [Omnibus GitLab issue](https://gitlab.com/gitlab-org/omnibus-gitlab/issues/4688) for more information.
+
+NOTE: **Note:** If Omnibus settings are present, applications settings will be automatically ignored to avoid generating multiple requests blocks.
+
+To migrate from Omnibus GitLab 12.3 and earlier settings:
+
+1. Disable the Protected Paths throttle from Omnibus, by changing `rack_attack_enabled` value to `false` on [`rack_attack.rb.erb`](https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/files/gitlab-cookbooks/gitlab/templates/default/rack_attack.rb.erb#L18):
+
+   ```ruby
+   rack_attack_enabled = false
+   ```
+
+1. Customize and enable your protected paths settings by following [Configure using GitLab UI](#configure-using-gitlab-ui) section.
+
+1. Restart GitLab:
+
+   ```bash
+   sudo gitlab-ctl restart
+   ```
+
+That's it. Protected paths throttle are now managed by GitLab admin settings.
