Large cookie size breaking login

This seems to be the same question that's already been asked, but it was a few months ago. I want to check if there's been an update since: https://discord.com/channels/1288403910284935179/1357381653067989214/1357381653067989214 I don't see why it's important to store the image in the cookie and then go over the browser limits. What we were able to do on NextAuth is just remove the image from the cookie. We store the image in the database, but it doesn't need to be stored on the cookie level. I'm curious, is there some way to do this in BetterAuth? This isn't a huge headache because this is quite a bad bug....

Renamed email field via auth config results in auth error

Using better-auth@1.3.8-beta.3 with prisma adapter I've renamed several columns via the auth config (to use snake case column names), and also changed the database column names (via prisma migration). But upon logging in there's a query error thrown which is attempting to use the custom field name email_address instead of the prisma model name email. auth.ts...

Trying to connect kysely-neon with Better Auth but failed.

I don't know what causes this, but apparently coming from the configuration. I already created my src/lib/auth.ts file inside my SvelteKit project. And this is my code: ```typescript import { betterAuth } from "better-auth";...

Email Verification Email is not Sent

I've been trying to add emailVerification to my app for some time, but didn't get it working. My function works well, doesn't have issues when trying it externally from better auth. But when I am trying to make it send the email, it does not work. ( Added prints and it looks like the function isn't called ) ```ts emailAndPassword: { enabled: true,...

Solution:

It looks like the verification email isn’t being sent because the configuration is misplaced. According to Better Auth’s documentation, options like sendOnSignUp and sendVerificationEmail should be defined under the emailVerification configuration rather than inside emailAndPassword. In your snippet, they’re currently under emailAndPassword, so the framework isn’t triggering the verification email on signUp [1], [4]. To fix this, move these options to the emailVerification object in your auth configuration. This should ensure that the email verification process is correctly triggered on signUp. Sources:...

Create a Magic-Link from the server

The documentation for creating a Magic-Link for signing in with auth.api.signInMagicLink mentions we have to set the headers ("This endpoint requires session cookies"), but I'm not sure which headers have to be given, when I'm doing the call from the server? Basically what I'm trying to do is using the magic-link as a kind of "invite" for users, so I have some script in my backend which automatically sends the magic-link to the new user. What should be the content of that header? it says it's for cookies, but I'm not using cookies when doing a call from the backend on the behalf of another user...

Server-side calls without request headers?

Hi, I was wondering if there’s a way to create users, send invitations, etc. purely from the server side, without having to pass through the request context or headers to the authClient.api.* functions. For example, is there a way to create an auth client that has a server secret token baked in or some other means of authentication that's baked into the client? Right now, if I want to build something like a generic user-invitation service, it feels awkward to either (a) not have the request handy, or (b) thread headers all the way down through multiple layers of my app just so I can call Better Auth in cases where, perhaps user invitations are sent as part of a larger complex workflow. What I’d really like is a way to make these kinds of trusted, server-initiated calls on behalf of the application itself (not tied to a logged-in user)....

Plugin Schemas

If I use prisma adapter, do I need to use my models in the plugin, rewrite the schema, or is there an automatic solution for creating a schema from prisma in json?

OIDC Login page question

I’m building an internal-only OIDC provider with Hono on backend.mydomain.com. All consuming services will be on the same parent domain (*.mydomain.com) and expect OIDC-compliant JWTs. Can I keep the actual login UI (username/password form, MFA, etc.) on a separate host—accounts.mydomain.com—while still having the OIDC discovery, token, and JWKS endpoints served from backend.mydomain.com? In other words, is it valid (and what do I need to configure) so that:...

How can I run a hook after the Google OAuth flow?

Hey, I'm in the process of migrating my previous custom auth logic to better-auth. I'm using better-auth on my Hono backend. I need to execute logic after the user completes the Google OAuth flow, I need to recreate a Postgres materialized view adding the newly create user. Previously I just had this logic in the handler itself but now I'm not sure where to add this logic. I'm trying to add this logic to a hook like so: ```hooks: {...

However, on devices other than iOS, authentication works without problems.

it takes me to the home page, but without logging me in. I tried this on different browsers on my iPhone, whether Safari, Chrome, or Brave, and none of them logged in or logged in, even though it took me to the home page without any errors. However, on devices other than iOS, authentication works without problems. Are you using session cookies? yes I use (I think this is the problem because I am using Lax=none because the domain of the frontend and backend are different.) ...
