I have been considering this since Apple Passwords implemented a way to export. I've just seen that the iPhone Passwords app has an export to another app you have installed on your phone, but I previously tested the export from Safari method.

I realise that this is moving even more of my eggs into Apple's basket, and even further from self-reliance towards convenience, but today it doesn't seem significantly worse to just trust Apple with this, than Bitwarden.

But isn't it a pain to use those passwords on any other non-Apple device? Am I missing something, or is that just not an issue for your use-case? Ah! I've just learned/relearned about iCloud Passwords through iCloud for Windows, but nothing for Linux?
