1password has support for a custom domain. I bought an old generic webmail provider domain that is now defunkt and use that. I also use random name aliases on each signup. Even if you aggregate multiple breaches I doubt anybody would link it to an individual (me). The big remaining issue is payments. I use multiple cards and rotate them regularly (I don't have access to privacy.com or similar where I am based). I believe this is the future - feed each service you signup to a new set of information and keep track in a password managers. Most services don't care what your real name is (I've been using an alias on services like Uber for ~10+ years). icloud is also a good option - but I don't want to signal being an iCloud user.
