I've been using 1Password for several years and I decided to try to migrate to the new Apple Passwords app.

Selecting "Export" from 1Password was easy enough, and importing these into the new Password app was pretty easy, but extremely slow. I was prompted to add a browser extension for the Brave browser but not for Chrome; not sure why.

But the screenshot below shows a bigger problem: Apple's massive ego decided that they are always more important than anybody else. Many, many years ago, I'd saved passwords into Apple's keychain. Since getting 1Password, I've replaced all of these passwords with far stronger passwords.... but on Import.... no date checking no prompting... Apple decided that they're so important that 84 of the passwords I imported couldn't be used. Great! Just 84 manual imports. Thanks, bozos.

84 Passwords couldn't be imported:
