Just for refence another way (that will in no way work on Windows) is to temporarily tweak the terminal attributes. The ocamlunix book shows how to do this [here][1].
In contrast to ANSI escapes which I believe is just a rendering trick that snippet will not allow to cut and paste the input password to recover it, whether that's a property you care about or not is up to your use case.
Best,
Daniel
