“And both Apple and Google prevent you from exporting your passkeys, meaning you’ll need to create them all over again if you want to switch to another password manager.”
Passkeys came out of the FIDO Alliance and the W3C as an open standard. Apple shipped them in 2022 to sync nicely across Macs and barely work on Windows.

A login you can’t export is a leash.
