Cannot find module 'better-auth/plugins/passkey' with Better Auth 1.4.x

[ethanaggor]

Problem

Upgrading to Better Auth 1.4.x fails because the adapter imports from better-auth/plugins/passkey, which no longer exists:

Cannot find module 'better-auth/plugins/passkey' from '@convex-dev/better-auth/dist/esm/auth.js'

Cause

Better Auth 1.4.0 moved the passkey plugin to a separate package @better-auth/passkey. The import in src/auth.ts line 17:

import { passkey } from "better-auth/plugins/passkey";

...needs to become:

import { passkey } from "@better-auth/passkey";

Impact

Better Auth 1.4.x includes security fixes (session fixation, path traversal). Users cannot upgrade without a workaround.

Workaround

Create a postinstall shim that patches better-auth/plugins/passkey to re-export from @better-auth/passkey (or a no-op stub if not using passkey).

Versions

• @convex-dev/better-auth: 0.9.11
• better-auth: 1.4.5

This component is not yet compatible with better-auth 1.4. Check https://convex-better-auth.netlify.app/framework-guides/react#install-packages : 1.3.34 only.

@pierre-H 1.3.34 had security issue, how can we use latest version of better auth with convex?

Only @erquhart has the answer ... We have to wait for an update of this component.

I see... @erquhart its on you then, please help us...

I looked at the migration guide and did a small PR, hope they fix it.
