Hi, @freelance123.
There aren’t any user account level settings, but this snippet may come in handy for restricting the quantity to 1 for each order submitted:

I hope it works well for you as-is or as a starter toward your own customization.
Marking Resolved due to lack of response.
Thank you @cliffpaulick for the snippet.
But, users can make a second separate registration.
On my website I reserve registrations only for logged in users. Can I block registration of registered users to 1 ticket per event?
Thank you !
Yes, users could make separate registrations. The snippet limits to one at a time, which can be especially useful if you want the name and email of each attendee.
I don’t know of a snippet to limit to one per event, but I’d guess it’s possible.
