In fact, I think it's technically possible. But it's true, as of today I don't think anybody supports it.
I was experimenting on solokeys with ios, in principle we could backup Passwords (the ios/mac app) into a solo key, space permitting, including passkeys, regular passwords and totp (not wifi passwords). I believe the same is for Android, but haven't tested yet. This is all experiments I've been doing on my own, there's nothing ready to be released.
- tadfisher 14d agoThat quote is referring to the mechanism for backing up passkeys that only exist on a hardware security key, which deliberately does not exist. Moving keys onto a security key is possible for some devices, but that is a deliberate compromise, as these devices are designed to generate their own keypairs and never leak secret key material (thus preventing backups).
- ecesena 14d agoOps, I may have misinterpreted. I read it as take a passkey and copy/store it inside a hw sec key. Thanks for clarifying!
