# Captcha

Config path: `checks.chat.captcha`\
Permission (bypass): `nocheatplus.checks.chat.captcha`\
Exemption: `CHAT_CAPTCHA`\

The captcha feature can be used together with our text or commands spam check to ask players that fail one/both of those a randomly generated captcha, which needs to be answered in order to continue.

| characters | Which chars (numbers, letters and symbols) should be used to generate a captcha?                                                                                                    |

| question   | The message that will be sent to players upon triggering a chat-related check (Text/Commands), the text \[captcha] will be replaced with the actual captcha.                        |
| success    | Set the message which will be shown to the player if they answer correctly.                                                                                                         |
| tries      | Max tries before a player will get kicked from the server. Be generous here, as players may not be fast enough to read the question the first few times or be otherwise distracted. |
