First, having recently switched to 1Password from LastPass, I wish I'd made the switch a long time ago. Some parts of the UI are simply different, but most of it is a lot better. And the security is clearly a lot better.
BLUF: The main thing that's missing for me (and LP didn't do this well, either) is a way to sort and filter based on password age. The modification date is useful, but the date I changed the tags or added a note is almost useless to me. The date I most recently changed the password is.
First, I'm not interested in password rotation generally. I am grateful that NIST 800-63-3 finally made the comment that forced password changes are counterproductive. One should, generally, only change strong passwords when there's a good reason to do so. And I can go into any given 1Password item and see when I last changed that password.
However, I think there are a couple of use cases where being able to sort things by password age is a useful feature.
1) in a case like mine, where I've switched to 1Password due to a different product's f-up. Because of the LastPass breach, I am changing every single password. I've done all of the critical ones, but there are about 1000 items in my vault. I need to review all of them. Sorting by modification date is a good start, but it's only a correlated variable. I've changed tags on some things, doing bulk tagging based on some searches, to help me prioritize which passwords needed to be changed first. I really want to be able to sort on password age, so that I can go through and make sure that I have changed all of the passwords.
2) While strong passwords don't need to be changed in the absence of a good reason, what constitutes strong does change over time. I was a LP user for well over a decade. What constituted a strong password back then isn't the same as what constitutes one now. Some sites had limitations on password length -- I can think of several that limited passwords to 16 characters. My opinion is that periodically (once a year or so), taking a look at my oldest passwords and deciding if they should be changed, is a reasonable security practice (on top of services like WatchTower). Now services like Watchtower go a long way on that, particularly in terms of highlighting what are understood to be weak passwords. But, I'd argue that reviewing the oldest passwords on a very periodic basis, such as by exposing a "sort by password age" is a reasonable security practice.
