According to the information provided in the knowledge sources, captcha protection in Ory Identities is currently being tested and is not yet available for general use. However, here's what we know about the planned captcha support: 1. Ory Identities plans to support protecting registration and login endpoints with captcha challenges [Ory Docs: CAPTCHAs](https://www.ory.sh/docs/kratos/concepts/security#captchas). 2. The purpose of this feature is to prevent credential stuffing, brute force, and other automated attacks. 3. Currently, the only supported captcha provider mentioned is Cloudflare Turnstile. 4. There are UI messages implemented for captcha-related actions, such as prompting users to complete the captcha challenge and notifying them of failed verifications [Ory Docs: UI Messages](https://www.ory.sh/docs/kratos/concepts/ui-messages#please-complete-the-captcha-challenge-to-continue-1070015). Since this feature is not yet generally available, if you're interested in using captchas with Ory Identities, you should [contact Ory](https://ory.sh/contact) for more information about its availability and implementation.
