Are there any password managers that
- Integrate into browsers on all major platforms
- Have decent password generators
- No major security breaches in past ten years
- Local-first / sync via standard sync mechanisms (Dropbox, iCloud, sync thing, etc.)
EDIT: Based on responses below, I'm going to try KeePass[.*] and see how it goes. First hiccup is that 1Password import doesn't seem to work, but I'll keep at it.
