`trustedProviders` is not respected with social login

Author: jvllmrCreated Sep 17, 2026Updated Sep 17, 2026

Is this suited for github?

Yes, this is suited for github

Reproduction

Configure auth with genericOAuth/Social plugin
Set providerId from genericOAuth in account.trustedProviders setting
Try to login with unlinked account. Error is raised because account is not linked

Current vs. Expected behavior

Currently I expect a forced link to happen as described in https://better-auth.com/docs/concepts/users-accounts#forced-linking , but instead I receive an error page. Only workaround right now is to set requireLocalEmailVerified to false.

What version of Better Auth are you using?

1.7.4

Backend

Auth config (if applicable)

typescript

import { betterAuth } from "better-auth"
export const auth = betterAuth({
  emailAndPassword: {  
    enabled: true
  },
});

Additional context

I assume this is because trustProvidersByName is not set to true here: https://github.com/better-auth/better-auth/blob/641630f06c128e786fd6a710b075e41e9f9adec9/packages/better-auth/src/api/routes/callback.ts#L372
