Unity - SignInWithApple how to use rawnonce-nonce

[Muhsin Ege]

Hi everyone,

We are trying to provide multiple authentication options for our users, I have managed all the other authentication providers but SIWA. Tried to read every document and looked at the quickstarts but there are no information about how to use nonce and rawnonce.

I have generated random string which has a length of 32 as a rawnonce and sha256 copy of it as a nonce, I understand that i need to pass the rawnonce string to firebase for authentication but i have no clue what do whit the nonce?

Have some questions about it for understanding how it works, if a user deletes the game or clear the cache, i have to generate new rawnonce and nonce. Will it authenticate the user without problem? It says store the sha256 version of nonce but is it possible to store it permanently on a device?

Thanks for all the information! Cheers :)

HI Muhsin,

I've created a reply to your post in the Unity Quickstart with an example on how to edit the SignInWithApple Unity plugin so that it uses a nonce when creating the SignInWithApple request.  Please look it over and reply to that post with any questions or problems that you have.

Unfortunately storing nonces isn't possible. A nonce is essentially  `a random number used only once` and is used here to prevent replay attacks -- you will need to regenerate the Nonce and SignInWithApple requests for every auth operation.

Best regards,

Dave Della Bitta
