I'm not against passkeys. They have some real advantages. And I understand more than you think.

My comment is primarily about the preferred ecosystems that tend to come along with these newer solutions (like Apple's iCloud or Google's Password Manager) and how the corporations take advantage of user laziness and bandwagon jumping.

They may not force you to be exclusive with them, but they definitely want you to be. And over time they will likely make it more and more inconvenient not to be locked in with them.

For contrast, I use BitWarden for password management and Bitwarden Authenticator for TOTP (and I keep safe copies of TOTP secret keys elsewhere). This is a generic open-standards-first approach to things, with relatively easy recovery should you lose something. You can export your passwords. You have copies of your secret keys. You are in no way locked in to BitWarden forever.

Passkeys can also work within that type of operational framework! Like TOTP which normally uses RFC6238, Passkeys tend to use CTAP or WebAuthn. All of the above are open standards. And this is a good thing!

But do you really think Apple, Google, Microsoft, etc, want to play nice long term? Hopefully they will. But I have also run into evil nonsense like LastPass, which even though they also used open standards, their software would not allow you to do simple things like recover your own secret keys, export your data, etc. (Not to mention the embarrassing security breach they had and the wretched response, the main reasons to dump them).

While I am not directly comparing an idiot company like GoTo Tech with Apple et al, they all have the same types of big brain MBA types working for them who love to constantly brainstorm new ideas on how to screw the users over by taking features away and calling it a "software upgrade".

So, passkeys as a security mechanism: sure, this gets my vote. But trusting the big corporations not to change the rules on us later....come on, get real. They love limiting or removing portability and recovery options whenever they can.

Bottom line: don't assume passkeys are inherently good or bad. It's simply a security standard that can work well if implemented correctly. Passkeys make logging in easier. But will they also make recovery / export / migration easier....? Because if it's not easy, people won't do it.
