Yeah, these all look obviously correct. I suspect most people haven't
noticed them because it's pretty easy to use a real password helper
these days instead of shoving it into the URL.

Looking at the code, I think we'd keep the trailing slash during the
anonymization. Good.

Sort of orthogonal to your patch, but these could probably stand to be
marked for translation (I'm happy for that to come on top later,
though).

Good attention to detail here.
