> I feel like it's extremely common for the autofill to not work for various reasons even when you aren't being phished

I dunno, it mostly seems to not work when companies change their field names/IDs, or just 3rd party authentication, then you need to manually add domains. Otherwise my password manager (1Password) works everywhere where I have an account, except my previous bank which was stuck in the 90s and disallowed pasting the passwords. If you find that your password manager doesn't work with most websites (since it's "extremely common") you might want to look into a different one, even Firefox+Linux combo works extremely well with 1Password. Not affiliated, just a happy years+ user.

Yeah, I've looked into Passkeys but without any migration strategy or import/export support (WIP last time I looked into it), it's not really an alternative just yet, at least for me personally. I have to be 100% sure I can move things when the time ultimately comes for that.

I'm glad you've had such good experience with autofill consistently working for you. My experience has been closer to that of the sibling comments: 60/40 so I often just give up and copy-paste. I actually did try jettisoning 1Password for Proton Pass but that was even worse, so I went back

> without any migration strategy or import/export support

Since you're already a 1Password user, I wanted to draw your attention to the "Show debugging tools" in the "Settings > Advanced" section. From that point, you can say "Copy Item JSON" and it will give you the details you would want for rescuing the Passkey. Importing it into something else is its own journey that I can't help with

  {
    "overview": {
      "passkey": {
        "credentialId": "...",
        "rpId": "example.com",
        "userHandle": "..."
      },
    ...
    "details": {
      "passkey": {
        "type": "webauthn",
        "createdAt": 175.......,
        "privateKey": "eyJ...",
        "userHandle": "..."
      }

My understand is the people behind passkeys are working on an import/export solution. Who knows when it'll happen though.

For now, when companies let me have multiple passkeys, that's sufficient for me. I put one on my Apple Keychain and one in 1Password.
