You create an additional passkey for that device, or use a password/passkey manager that syncs your passkeys across devices.
(Note: I've actually done the former with my Google account. I'm waiting for passkey support in 1Password to test the latter scenario, but believe this is how it'll work.)
- Zamicol 3y agoI do not believe this is true. Passkey is only a 1 user, 1 key system. This means that to login on a second device, the 1. key must be exported from the first device, 2. encrypted, and 3. transferred to the second device. Each device needs a copy of the private key.
- kccqzy 3y agoYou can add multiple passkeys on your Google account today. If a website is dumb enough that they only allow a single passkey per account, they have misunderstood passkeys profoundly.
- Zamicol 3y agoGoogle != passkeys. Google may allow multiple keys, but that is outside of what FIDO specifies for passkeys. Here's a source saying that passkeys expect one and only one key: https://auth0.com/blog/our-take-on-passkeys/ https://auth0.com/blog/our-take-on-passkeys/ "Passkeys are designed to [...] allow the FIDO credential to roam across multiple devices. This [means that there's ] no need to repeat enrollment on each device [.]" > If a website is dumb enough that they only allow a single passkey per account And that's exactly my point.
