I have 728. Before Bitwarden I used password store. I migrated with a script about 2 years ago, and I still don't have all the necessary metadata in at least a half (meaning there is no icon, usernames are messy, etc). I only update the old entries whenever the accounts are needed, meaning that I haven't used half of them in 2 years. So I "actively" use about 360 accounts on various services.
