The Portal rate limitin settings enable you to prevent a user or bot from carrying out the same action repeatedly within a short period of time.

For each action that has a rate limiting setting, you can define how many times within which period of time the same user must do the action before triggering rate limiting.

You can also choose what to do when rate limiting is triggered:

• show a CAPTCHA to the user
• disable that action for the user

See the CAPTCHA settings section for more options to do with CAPTCHAs.
