Set rate limit on password reset Started By willem DNN does not apply rate limiting to incoming requests. The endpoint for requesting a password reset link accepted repeated consecutive requests, with the server returning an HTTP 200 response each time. No blocking, throttling, CAPTCHA, temporary lockout, or HTTP 429 'Too Many Requests' response was observed. Is there a way to set a rate limit (retry limit) on password reset		198	0	8/26/2026 8:23 AM by willem

I cannot uninstall this leftover from the UI, as it is marke...	3	3128	0	11/4/2020 2:53 AM by Michael Tobisch

Cookie consent options for allowing/declining Started By Intellicom Hello, We are using the built-in DNN cookie consent feature in Site Settings > Site Behavior > Privacy, which is working and shows the message with the 'Got it!' button. I saw on the homepage of the dnnsoftware.com website though that it looks like they may be using the same built-in cookie consent (based on what I see when inspecting the HTML) but they have options to either 'Allow cookies' or to 'Decline'. Is this possible to do with the built-in cookie consent on our DNN sites I am te...	1	181	1	7/13/2026 9:35 AM by Intellicom
