Unfortunately LastPass had some issues over the past years with hacking where encrypted vaults were stolen. Between myself and my friends in tech, I know of a few conpanies that ditched it after that.

For individual/personal use, I’d reccomend KeePass (whatever fork of it is up to date and maintained lately) and using somethung like syncthing to sync it across devices. That may not be super user friendly for non-technical users though, and I’m not sure how well it works with iPhones.
