# Enabling registration
|
||
|
|
|
||
|
|
Enabling registration allows users to register their own user accounts on your
|
||
|
|
Dendrite server using their Matrix client. They will be able to choose their own
|
||
|
|
username and password and log in.
|
||
|
|
|
||
|
|
Registration is controlled by the `registration_disabled` field in the `client_api`
|
||
|
|
section of the configuration. By default, `registration_disabled` is set to `true`,
|
||
|
|
disabling registration. If you want to enable registration, you should change this
|
||
|
|
setting to `false`.
|
||
|
|
|
||
|
|
Currently Dendrite supports secondary verification using [reCAPTCHA](https://www.google.com/recaptcha/about/).
|
||
|
|
Other methods will be supported in the future.
|
||
|
|
|
||
|
|
## reCAPTCHA verification
|
||
|
|
|
||
|
|
Dendrite supports reCAPTCHA as a secondary verification method. If you want to enable
|
||
|
|
registration, it is **highly recommended** to configure reCAPTCHA. This will make it
|
||
|
|
much more difficult for automated spam systems from registering accounts on your
|
||
|
|
homeserver automatically.
|
||
|
|
|
||
|
|
You will need an API key from the [reCAPTCHA Admin Panel](https://www.google.com/recaptcha/admin).
|
||
|
|
Then configure the relevant details in the `client_api` section of the configuration:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
client_api:
|
||
|
|
# ...
|
||
|
|
registration_disabled: false
|
||
|
|
recaptcha_public_key: "PUBLIC_KEY_HERE"
|
||
|
|
recaptcha_private_key: "PRIVATE_KEY_HERE"
|
||
|
|
enable_registration_captcha: true
|
||
|
|
captcha_bypass_secret: ""
|
||
|
|
recaptcha_siteverify_api: "https://www.google.com/recaptcha/api/siteverify"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Open registration
|
||
|
|
|
||
|
|
Dendrite does support open registration — that is, allowing users to create their own
|
||
|
|
user accounts without any verification or secondary authentication. However, it
|
||
|
|
is **not recommended** to enable open registration, as this leaves your homeserver
|
||
|
|
vulnerable to abuse by spammers or attackers, who create large numbers of user
|
||
|
|
accounts on Matrix homeservers in order to send spam or abuse into the network.
|
||
|
|
|
||
|
|
It isn't possible to enable open registration in Dendrite in a single step. If you
|
||
|
|
try to disable the `registration_disabled` option without any secondary verification
|
||
|
|
methods enabled (such as reCAPTCHA), Dendrite will log an error and fail to start.
