Thanks for the correction and clarification, guys! In retrospect, of course you’re right, it wouldn’t make sense to use the Secure Enclave for arbitrarily large amounts of data.
Here’s a useful blog post from Troy Hunt that does a much better job of explaining Passkeys than I have been able to do.
I think it may be useful for some of the users following this topic.
I didn’t realize until today that Troy (a MS MVP) was being Have I Been Pwned, and that they have also recently formed a partnership with 1Password.
A followup to my own post from a month ago. After finally upgrading to 1Password 8 on my Mac, I realized that I should update to it on my iPhone and iPad as well. On macOS, the 1Password 8 install will automatically archive the 1Password 7 app (into a ZIP file), but under iOS I had to delete the “1Password 7” app after installing “1Password” (version 8 doesn’t have an 8 in its name).
I also finally took the time to turn off Apple’s Passwords app entirely, so I don’t have two sources competing to auto-fill fields in Safari, generate new random passwords, or offering to store those passwords. I had to generate new Passkeys with 1Password to replace a few I had created in Apple Passwords, but otherwise I continue to be happier with 1Password 8 than 7.
