largeBlob support in passkeys?

Hi 1P_Dave​,

I'm just following up on my previous message. Is adding largeBlob support something you would still be willing to file a feature request for?

Let me know if there are any more details you would like from our use case.

Many thanks,

Joe

I would need largeBlob in my local-first webapp to store end-to-end encryption password on the key.

That sounds like a interesting use of the largeBlob extension! While I can't make any promises, I've filed a internal feature request on your behalf and the team will look into the feasibility and value of supporting largeBlob in the future.

Thank you for the feedback!

Sure! What I'm trying to do is simplify management (and sync) of E2E encryption keys. So when you sign up for an account, you register a passkey, and your browser uses its https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto to generate a couple keypairs (for signing and key exchange). I send the public keys to the server, and store the private keys alongside the passkey (using the largeBlob extension). It's totally transparent to the user, the private keys never touch my server, and it syncs to all their devices automatically - no scanning QR codes or implementing my own key wrapping/syncing mechanism.

Thanks so much for the response - a feature request would be lovely! And let me know if you'd like any more information.

Thanks,
Dan

Hello @dcwatson! 👋

Thanks for the question! 1Password doesn't currently support the largeBlob extension for passkeys and I haven't seen too many requests for support come in yet. Can you tell me a little more about the data that you'd like to store with the passkey? I would be happy to file a feature request on your behalf with our product team.

I look forward to hearing from you.
