Alice's Password PC code puzzle is too hard


Are there someone can explain to me to get easier ?
actually, it's very simple, only you just have to waste some time with it. so you have a password of 5 symbols, which could be repeated (v important!), when you try you have on the left 2 indicators one (
yellow) shows the number of symbols guessed, the other (
green) the ones positioned correctly, so you need
55 there! First try all the symbols choosing a single symbol in all positions at the same attempt, with this you eliminate those symbols that do not exist at all in the password(
00), then try the symbols that were found only once (
1 with 0 or 1) to establish their exact position on the 5 ones (
1), using that symbol from those that are not in the password (
0), after establishing those in position the remaining ones that are more than
1 will complete the remaining positions!
