Demona's preferred option is Cloudflare Turnstile: it is free and avoids the behavioural profiling associated with Google's reCAPTCHA. If you use reCAPTCHA, make sure your privacy information reflects the data sent to Google.
Turn it on
- In the provider's dashboard, create a key pair for your website domain. You need a site key (public) and a secret key.
- Select the provider here.
- Paste both keys and save.
When you save, Demona validates the secret key with the provider. If the provider rejects it, you see an error. A common cause is pasting the public site key into the secret-key field. The secret key is stored encrypted and is only sent server-side to the selected provider when needed.
Note: reCAPTCHA v2 and v3 use different key pairs and cannot share the same credentials. Switching provider removes the stored captcha key pair, so enter new keys for the provider you choose.
