Fingerprint / Token authentication

Hi all!

I am trying to check out appwrite if it will allow me to incorporate it in my next project. I have appwrite up and running and a few endpoint implemented and I like it so far.

I wanted to see now if I'll be able to login users with a "fingerprint" from a mobile device. Say String "123" for test purpose. I tried using: https://appwrite.io/docs/products/auth/custom-token But I don't have account.createSession in JS.

Please can you advice how can I achieve this ? 🙂 Many thanks!

TL;DR

Developers are discussing fingerprint/token authentication. They clarify the usage of `createToken` on the server and `createSession` on the client. A link to a custom flow implementation is shared. `account.createSession()` is only for the server-side. A developer is looking to log in users via "fingerprint" on a mobile device using Appwrite and encounters an issue with JS.

account.createSession() is only available on server-side.

Where are you trying to sign the user into?

Nice catch, createToken should run on server (Server SDK), and createSession on client (Client SDK).

Here is passkey I implement in free time, it showcases a custom flow as well: https://dev.to/meldiron/biometric-authentication-with-passkeys-3e1

I dont know how exactly fingerprint ID works in mobile apps, but I can imagine it is similar handhsake/challegne approach.

Oh, whoops - looks like I got them mixed up!

Well you spotted it, close enough 😝 I was already digging in docs if it's createTokenSession 🙈
