Question about Watchtower vulnerable password integration with haveibeenpwned.com.

Hi there thedean

Watchtower checks haveibeenpwned.com every 24 hours, or if an item is edited, whichever comes first. So to answer your follow-up question, if there's a new report on havibeenpwned.com, any of your items that match will be flagged within a day.

As far as workload on your device is concerned, the hashing isn't likely to be much more than what happens when you unlock 1Password with your account password, which already involves a few hundred thousand rounds of hashing. Considering how quickly unlocking 1Password happens, it's reasonable to assume that the Watchtower checks can be performed within the same sort of timescale – a matter of seconds, even if you have lots of items.

I hope that answers your question, but I'll be here if you need anything. :)
