Hi @phi1ipp
Thank you for reaching out to us!
At this moment there is no option of counting or setting a limit to the number of incorrect OTP attempts within Forms. The standard limit is 10 attempts, after which the user is forced to re-send the OTP and generate a new one. You can find more information on our Knowledge Article.
If you would want, you could you create a Feedback request asking to implement the possibility of a count or limit of the incorrect OTP attempts.
The feedback request includes a voting system where feedback requests with higher votes have higher implementation priority.
Have a great one!
Gerald
