PROBLEM with passwords

I have yet to try out the same number of chars being typed per key press but as far as i know the p key makes 3 chars appear (typed "password" many times trying to get into my modem though it affects other password fields like target's but not those of southperry or maple) but for the most part i think its the order that affects it as in the first key makes 3 appear no matter what key is pressed

just tried it pressing random keys as the first position and it seems to always give the same pattern 3-2-2-2-3-3-2 (end of the password field so not sure on last number) I tested it with all s and all a and yielded that same pattern
