Passkeys are a nice solution, and it's entirely possible to adopt them without locking yourself into Apple or Google's walled garden. That seems to require you to forgo using your Apple/Google devices as passkeys themselves, unless you use an unrelated app as your passkey manager. It's interesting seeing how they're being used for lock-in, though. As mentioned in this thread, attestation in the standard will be abused towards that end.
