I have a question about how my bank implements passwords. I feel like the way the input works they can't be hashing in a safe way. Would it be on topic to show the input screen and ask if there is a way this could be implemented securely?
Questions on "How to do it?" are on-topic here (and I said "How to do it?", not "Do you mind make it for me?" which is a different thing ;) ).
At the opposite, questions on "How it's done?" are most often flawed (except in a few cases like open source projects for instance where everyone is free to check how it has been done), since anyone can just guess and express suppositions with no clear facts or answers.
And usually, the lack of facts and clear answer is no good on such a Q&A website.
P.S.: Another related question which I think to be on topic would be "What security does it bring?", since it is less dependent on the internal implementation and allows to develop clear answers on the threat models (or the lack of...) addressed by the described solution.
