I’m surprised @texnixe! Is this at all documented somewhere? I found nothing in the references, the security guide (which then contains a misleading sentence about bruteforcing Kirby 3) and only outdated posts on this then. I did some research in the past before I wanted to do this and I found zero information about this.
Edit: I found this How does Kirby 2.2 bruteforce protection work? and Is Kirby secure?. Seems like the first time I didn’t find the first thread. Seems like there is a bruteforce protection beginning to ban after 5 (?) tries. At least it triggered before 10 times.
