Set custom strategies for ID generation and findMany queries.
* `generateId`: Controls how record IDs are generated. Accepts a custom function, `false`, `"serial"`, or `"uuid"` (default: [random base62 string](https://github.com/better-auth/better-auth/blob/main/packages/core/src/utils/id.ts)). See the [Database documentation](/docs/concepts/database#id-generation) for more info.

```ts
import { betterAuth } from "better-auth";
export const auth = betterAuth({
advanced: {
database: {
generateId: "uuid",
defaultFindManyLimit: 50,
