+
+The `<username>` must be an existing, provisioned user, as defined in the `auth-users` section (see [users via the config](#users-via-the-config)).
+The `<token>` is a valid access token, which must start with `tk_` and be 32 characters long (including the prefix). You can generate
+random tokens using the `ntfy token generate` command. The optional `<label>` is a human-readable label for the token, 
+which can be used to identify it later.
+
+Once configured, these tokens can be used to authenticate API requests just like tokens created via the CLI.
+For usage examples, see [authenticate via access tokens](publish.md#access-tokens).
+
+Here's an example:
+
+=== "Declarative tokens in /etc/ntfy/server.yml"
+    ``` yaml
+    auth-file: "/var/lib/ntfy/user.db"
+    auth-users:
+      - "phil:$2a$10$YLiO8U21sX1uhZamTLJXHuxgVC0Z/GKISibrKCLohPgtG7yIxSk4C:admin"
+      - "backup-service:$2a$10$NKbrNb7HPMjtQXWJ0f1pouw03LDLT/WzlO9VAv44x84bRCkh19h6m:user"
+    auth-tokens:
+      - "phil:tk_3gd7d2yftt4b8ixyfe9mnmro88o76"
+      - "backup-service:tk_f099we8uzj7xi5qshzajwp6jffvkz:Backup script"
+    ```
+
+=== "Declarative tokens via env variables"
+    ```
+    # Comma-separated list
+    NTFY_AUTH_FILE='/var/lib/ntfy/user.db'
+    NTFY_AUTH_USERS='phil:$2a$10$YLiO8U21sX1uhZamTLJXHuxgVC0Z/GKISibrKCLohPgtG7yIxSk4C:admin,ben:$2a$10$NKbrNb7HPMjtQXWJ0f1pouw03LDLT/WzlO9VAv44x84bRCkh19h6m:user'
+    NTFY_AUTH_TOKENS='phil:tk_3gd7d2yftt4b8ixyfe9mnmro88o76,backup-service:tk_f099we8uzj7xi5qshzajwp6jffvkz:Backup script'
+    ```
+
+In this example, the `auth-users` section defines two users, `phil` and `backup-service`. The `auth-tokens` section
+defines access tokens for these users. `phil` has a token `tk_3gd7d2yftt4b8ixyfe9mnmro88o76`, while `backup-service`
+has a token `tk_f099we8uzj7xi5qshzajwp6jffvkz` with the label "Backup script".
+
+### Example: Private instance
+The easiest way to configure a private instance is to set `auth-default-access` to `deny-all` in the `server.yml`,
+and to configure users in the `auth-users` section (see [users via the config](#users-via-the-config)), 
+access control entries in the `auth-access` section (see [ACL entries via the config](#acl-entries-via-the-config)),
+and access tokens in the `auth-tokens` section (see [access tokens via the config](#tokens-via-the-config)).
+
+Here's an example that defines a single admin user `phil` with the password `mypass`, and a regular user `backup-script`
+with the password `backup-script`. The admin user has full access to all topics, while regular user can only
+access the `backups` topic with read-write permissions. The `auth-default-access` is set to `deny-all`, which means
+that all other users and anonymous access are denied by default.
+
+=== "Config via /etc/ntfy/server.yml"
     ``` yaml
     auth-file: "/var/lib/ntfy/user.db"
     auth-default-access: "deny-all"
+    auth-users:
+      - "phil:$2a$10$YLiO8U21sX1uhZamTLJXHuxgVC0Z/GKISibrKCLohPgtG7yIxSk4C:admin"
+      - "backup-script:$2a$10$/ehiQt.w7lhTmHXq.RNsOOkIwiPPeWFIzWYO3DRxNixnWKLX8.uj.:user"
+    auth-access:
+      - "backup-service:backups:rw"
+    auth-tokens:
+      - "phil:tk_3gd7d2yftt4b8ixyfe9mnmro88o76:My personal token"
     ```
 
-After that, simply create an `admin` user:
-
-```
-$ ntfy user add --role=admin phil
-password: mypass
-confirm: mypass
-user phil added with role admin 
-```
+=== "Config via env variables"
+    ``` yaml
+    NTFY_AUTH_FILE='/var/lib/ntfy/user.db'
+    NTFY_AUTH_DEFAULT_ACCESS='deny-all'
+    NTFY_AUTH_USERS='phil:$2a$10$YLiO8U21sX1uhZamTLJXHuxgVC0Z/GKISibrKCLohPgtG7yIxSk4C:admin,backup-script:$2a$10$/ehiQt.w7lhTmHXq.RNsOOkIwiPPeWFIzWYO3DRxNixnWKLX8.uj.:user'

+### ntfy server v2.15.0
+Released Nov 16, 2025
+
+This release adds a `require-login` flag to topics, which forces users to log in before they can
+use the web app. This is useful for self-hosters and will obviously not be enabled on ntfy.sh.
+
+**Features:**
+
+* Add `require-login` flag to redirect to login page if not logged in ([#1434](https://github.com/binwiederhier/ntfy/pull/1434)/[#238](https://github.com/binwiederhier/ntfy/issues/238)/[#1329](https://github.com/binwiederhier/ntfy/pull/1329), thanks to [@theatischbein](https://github.com/theatischbein) for implementing most of this)
+
+**Bug fixes + maintenance:**

+* Add build tags `nopayments`, `nofirebase` and `nowebpush` to allow excluding external dependencies, useful for
+  packaging in Debian ([#1420](https://github.com/binwiederhier/ntfy/pull/1420), discussion in [#1258](https://github.com/binwiederhier/ntfy/issues/1258), thanks to [@thekhalifa](https://github.com/thekhalifa) for packaging ntfy for Debian/Ubuntu)

+## ntfy Android app v1.17.8
+Released September 23, 2025
+
+This is largely a maintenance update to ensure the SDK is up-to-date.
+
+**Features:**
+
+* Markdown is now rendered if "Markdown: yes" was passed ([#310](https://github.com/binwiederhier/ntfy/issues/310), thanks to [@NiNiyas](https://github.com/NiNiyas) for reporting)

+Released August 5, 2025
+
+This release adds support for [declarative users](config.md#users-via-the-config), [declarative ACL entries](config.md#acl-entries-via-the-config) and [declarative tokens](config.md#tokens-via-the-config). This allows you to define users, ACL entries and tokens in the config file, which is useful for static deployments or deployments that use a configuration management system.
+
+It also adds support for [pre-defined templates](publish.md#pre-defined-templates) and [custom templates](publish.md#custom-templates) for enhanced JSON webhook support, as well as advanced [template functions](publish.md#template-functions) based on the [Sprig](https://github.com/Masterminds/sprig) functions.

+    "body": "Hello ntfy Team,\n\nFirst off, thank you for developing such a powerful and lightweight notification app — it’s been invaluable for receiving timely alerts.\n\nI’m a user who relies heavily on ntfy for real-time trading alerts and have noticed that while push notifications arrive instantly, the in-app alert list does not automatically refresh with new messages. Currently, I need to manually pull-to-refresh the alert list to see the latest alerts.\n\nWould it be possible to add a feature that enables automatic refreshing of the alert list as new notifications arrive? This would greatly enhance usability and streamline the user experience, especially for users monitoring time-sensitive information.\n\nThank you for considering this request. I appreciate your hard work and look forward to future updates!",

+Package sprig provides template functions for Go.
+
+This package contains a number of utility functions for working with data
+inside of Go `html/template` and `text/template` files.
+
+To add these functions, use the `template.Funcs()` method:
+
+	t := template.New("foo").Funcs(sprig.FuncMap())
+
+Note that you should add the function map before you parse any template files.
+
+	In several cases, Sprig reverses the order of arguments from the way they
+	appear in the standard library. This is to make it easier to pipe
+	arguments into functions.
+
+See http://masterminds.github.io/sprig/ for more detailed documentation on each of the available functions.
