I'm trying to connect to analytics-store, which I was able to do earlier in the year though I haven't tried for some time, but am now being prompted for a password. I can SSH to bast1001.wikimedia.org no problem. As far as I recall I don't have a password set, but perhaps I've just forgotten it.
This could also be a similar issue to T163568, or I'm doing something stupid.
