Why is Ring allowing brute forcing? Individual cameras should be set to only allow logins at least a few seconds apart increasing up to several minutes and perhaps blocking IP addresses with excessive volume. If they're brute forcing Ring's servers an application firewall would catch and block this.
I don't think that the above comment means brute-forcing in the "try a million different passwords in a short time-period" sense, it's referring to finding a list of known password and email combinations and trying just those. I would expect that a few attempts wouldn't trip any brute-force alarms.
