Nothing of that?
You don’t need to export or know what is the key.
The key is different for each device.
Comment on Google will now make passkeys the default for personal accounts

I have a very long list of questions about PassKeys and none of this articles explains them well enough.
- Does Android have it build in AOSP or Google Play Services?
- Would it be possible to actually see your private key on Android? Like export them to a file?
- Does they work without third party service? Can it be just me and the service I am logging in, or does it require my servers from PassKey provider (like Google, Bitwarden, 1Password) to work?
- Can it be used offline? For example, can an offline device create token that second online device could use for login? (Like TOTP codes).
- Does they work on other Internet services than the Web? In other words, does they work purely over HTTP and webviews or can they be in future used to login in for ex. SSH servers?

But is it possible in the implementation of Android/iOS?
Backups are a thing. With SSH keys I have different key for every device too, but as they are stored in an accessable file (as all computer data should be) they are backed up with the rest of the system.

So first, no, all the fils should be accessible : There are special not “files”, but keys, like the key used for thys system. These keys pose a huge security risk of they are leaked somehow. The key can be something used to encrypt the device/disk. Encrypt a connection, and other things associated with encryption.
And because of that security risk, they are often stored in a special chip or simulated chip (like the simulated tpm 2.0 on pc processors), and not just “stored” so any malware or who knows what can access them just by reading the drive.
Second, the key is never transfered. When you connect to another device, that other device will get another key. Or maybe could it be backed up somehow in case of recovery on another phone? But that would defeat the entire purpose of this.
How Google can do to allow you to connect to another device if the first one is lost, not sure. But it would certainly either ask for a password and a 2fa method.

That’s the key question. From what it seems, it would replace a password manager with different passwords for each website, but you give Google control of the master password.

Keys are stored in the equivalent of iOS’s Secure Enclave (actual name is implementation specific: ARM’s TrustZone, Samsung’s KNOX, Pixel’s Titan M, etc): howtogeek.com/…/your-smartphone-has-a-special-sec…

I just replaced my iPhone, and the few places I “sign in with Apple” still work in the new phone. Yes, you can back it up and restore to a different device. I assume you can also use it across devices but I haven’t tried that

This is something different to PassKeys. “Sign in with Apple” is Apple telling online service “let him in”, while PassKeys is storing your authentication data on your device.

Yes, but that’s missing the important part.
Passkeys is not primarily about asymmetric keys. It’s about applying asymmetric keys to the Web as an open standard.
The W3C Web-Authn standard is what makes it important and revolutionary.
This is just as important as HTML, CSS and ActivityPub.
Finally we have an open standard that integrates in the web and offers a high level of security.

Is that like TLS client-side certificates?
alvvayson@lemmy.world 1 year ago
It’s actually quite similar, yes, in the sense that it uses a public/private key pair linked to your account.
But this works on the application layer and you don’t use certificates.
Much easier to setup.

Just an example of protocol different than HTTP.
