Where are passkeys stored?

Hey @CCal, thanks for reaching out. When a passkey is created, the private key is stored in your 1Password vault which is synced across all of your devices using the 1Password servers.

Keep in mind that a local copy of your data is also available on all of your devices. (This is why you can continue using 1Password even when you're offline). While connected to the internet, that local copy will sync and update any changes or additions made across your other devices.

Let me know if you have any further questions!

This is great. So, from what I am reading, it should not be necessary to set up a passkey on multiple devices (for the same site)? If I create a passkey through 1Password on my computer (example, Marketcircle's Daylite), the same passkey will work across all devices, and I don't have to create one for each device?

Hey @jbrowdy, that's correct. Any passkey you setup using 1Password will be available for use across all of your devices!

"When a passkey is created, the private key is stored in your 1Password vault which is synced across all of your devices using the 1Password servers."

That is completely incorrect!!!!

The private key for a passkey NEVER leaves the device's secure element (eg. TPM in Windows, Apple Secure Element, Android Keystore system ie. Trusted Execution Environment). The Android StrongBox Keymaster is actually a Hardware Security Module. There's no way to extract the private key that's the whole point of these security keys...

Your docs even state this:
https://blog.1password.com/passkeys-faqs/#:%7E:text=Each%20passkey%20consists%20of%20two%20parts%20%E2%80%93%20a%20public%20and%20private,want%20to%20log%20in%20to.

ok now I get what you were saying... this is the 1password passkey not authenticator passkeys. sorry!

Hey @NSAtech3, no worries - I appreciate you following up!

Don't hesitate to reach out if you ever have any questions.
