How do passkeys work across devices?

RGB3x3@lemmy.world to No Stupid Questions@lemmy.world – 58 points –

Let's start with a smartphone. A user creates an account with a passkey for a service, that passkey gets stored on their smartphone, and they can use biometrics to sign in from then on. The private key is stored on the smartphone. Great.

But then how do you sign into that same service from a different device?

If it's by using a password manager, some third party piece of software, How do you sign in on a device where you're not allowed to install third party software?

You don’t. Passkeys are very ecosystem-centric right now. If you are in apple, google, or Microsoft entirely, they will all allow you to move your passkeys around to different systems using the same basic mechanism they used for password keeping. Moving across ecosystems is absolutely broken - or rather - has never worked.

I think there are mechanisms to allow passkeys to work via Bluetooth or even via camera, as an external authenticator essentially, but I’ve never personally tried them.

Some password managers support passkeys, such as one password and proton pass, which will allow you to use multiple different devices. Personally, I am waiting for key pass to have proper support before starting to migrate to them.

Is keepass actually going to have support for passphrases? The author works in archaic ways and I have a feeling he's never going to truly support it.

Keepass or keepassxc? Xc i think is a community fork.

I mean regular keepass, I feel like XC is more likely to implement passkeys

Okay, I see I have never used a regular one. I think I read to use XC by default. Somewhere. And so that's the one I've always used. I've never even downloaded the original one.

I use camera one for github on a device outside my icloud, works great. A few websites also allowed me to add second passkeys (bitwarden in addition to icloud)

This doesn't exist

FYI there's a bug currently that lets everyone see the comment even after they are deleted

I use sync on android but I believe it's a bug in the API so it should be everywhere

Just try to reply to the comment and you'll see it
