I love the idea of duplicate detection. It helps me find redundancies. Unfortunately, it's super-limited sense of what is a duplicate means I tend to ignore it (and all other warnings) far more often than I should.
In every job I've had in the last 20 years there have been unified SSO which required different logins but kept the same password in sync. This has gotten even worse with the prevalence of cloud-based services which utilize unique formats for login to separate customers.
This is FYI a simple example, I've had as many as 7 variations at one job. All of these services authenticate against the same SSO, when I change my password it changes for all of them (otherwise I'd just use different passwords for each)
Now, I don't mind having to update my password N times. What bothers me is that 1Password goes to extreme lengths to warn me about reusing the password: inline warnings, popup warnings, etc. And what I've found is that I'm now "tuning out" to these warnings, and have stopped paying attention to them because they are prevalent. This caught me out the other day, where I overlooked a real duplicate because I'm blind to these alerts now.
