### Authentication
Depending on whether the server is configured to support [access control](config.md#access-control), some topics
may be read/write protected so that only users with the correct credentials can subscribe or publish to them.
To publish/subscribe to protected topics, you can use [Basic Auth](https://en.wikipedia.org/wiki/Basic_access_authentication)
with a valid username/password. For your self-hosted server, **be sure to use HTTPS to avoid eavesdropping** and exposing
your password.
To publish/subscribe to protected topics, you can:
Here's a simple example:
* Use [basic auth](#basic-auth), e.g. `Authorization: Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk`
* or use the [`auth` query parameter](#query-param), e.g. `?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw`
!!! warning
Base64 only encodes username and password. It **is not encrypting it**. For your self-hosted server,
**be sure to use HTTPS to avoid eavesdropping** and exposing your password.
#### Basic auth
Here's an example using [Basic auth](https://en.wikipedia.org/wiki/Basic_access_authentication), with a user `testuser`
and password `fakepassword`:

#### Auth Query Param
In some instances, you may want to send auth credentials in the URL (e.g., a GET webhook or a JSON POST request). You
can use the `auth` query parameter. Set the value to the base64 encoding of the value of the `Authorization` header
and strip any trailing `=`. **Be sure to only send auth credentials over an HTTPS connection**
To generate the `Authorization` header, use **standard base64** to encode the colon-separated `<username>:<password>`
and prepend the word `Basic`, i.e. `Authorization: Basic base64(<username>:<password>)`. Here's some pseudo-code that
hopefully explains it better:
Here is an example:
```
Step 1. base64(user:pass) -> base64(testuser:fakepassword) -> dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk
Step 2. Authorization header -> Basic base64(testuser:fakepassword) -> Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk
Step 3. base64(Authorization header) -> base64(Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk) -> QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw==
Step 4. remove trailing `=` (if any) -> QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw== -> QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw
Step 5. add query param to URL -> https://ntfy.sh/topic -> https://ntfy.sh/topic?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw
username = "testuser"
password = "fakepassword"
authHeader = "Basic " + base64(username + ":" + password) // -> Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk
```
!!! note
Do NOT remove trailing `=` after step 2
The following command will generate the appropriate value for you on *nix systems:
```echo -n "Basic `echo -n 'testuser:fakepassword' | base64`" | base64 | tr -d '='```
```
echo "Basic $(echo -n 'testuser:fakepassword' | base64)"
```
#### Query param
Here's an example using the `auth` query parameter:
=== "Command line (curl)"
```
curl \
-d "Look ma, with auth" \
"https://ntfy.example.com/mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw"
```
=== "ntfy CLI"
```
ntfy publish \
-u testuser:fakepassword \
ntfy.example.com/mysecrets \
"Look ma, with auth"
```
=== "HTTP"
``` http
POST /mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw HTTP/1.1
Host: ntfy.example.com
Look ma, with auth
```
=== "JavaScript"
``` javascript

method: 'POST', // PUT works too
body: 'Look ma, with auth'
})
```
=== "Go"
``` go
req, _ := http.NewRequest("POST", "https://ntfy.example.com/mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw",
strings.NewReader("Look ma, with auth"))
http.DefaultClient.Do(req)
```

Invoke-RestMethod -Uri $uri -Body $message -Method "Post" -UseBasicParsing
```
=== "Python"
``` python
requests.post("https://ntfy.example.com/mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw",
data="Look ma, with auth"
```
=== "PHP"
``` php-inline
file_get_contents('https://ntfy.example.com/mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw', false, stream_context_create([
'http' => [
'method' => 'POST', // PUT also works
'header' => 'Content-Type: text/plain',
'content' => 'Look ma, with auth'
]
]));
```
To generate the value of the `auth` parameter, encode the value of the `Authorization` header (see anove) using
**raw base64 encoding** (like base64, but strip any trailing `=`). Here's some pseudo-code that hopefully
explains it better:
```
username = "testuser"
password = "fakepassword"
authHeader = "Basic " + base64(username + ":" + password) // -> Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk
authParam = base64_raw(authHeader) // -> QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw (no trailing =)
// If your language does not have a function to encode raw base64, simply use normal base64
// and REMOVE TRAILING "=" characters.
```
The following command will generate the appropriate value for you on *nix systems:
```
echo -n "Basic `echo -n 'testuser:fakepassword' | base64`" | base64 | tr -d '='
```
