    DynamoDB Adapter - NextAuth.js

    Open Source. Full Stack. Own Your Data.

    Build Test Bundle Size @next-auth/dynamodb-adapter Version


    This is the AWS DynamoDB Adapter for next-auth. This package can only be used in conjunction with the primary next-auth package. It is not a standalone package.

    You need a table with a partition key pk and a sort key sk. Your table also needs a global secondary index named GSI1 with GSI1PK as partition key and GSI1SK as sorting key. You can set whatever you want as the table name and the billing method.

    If you want sessions and verification tokens to get automatically removed from your table you need to activate TTL on your table with the TTL attribute name set to expires

    You can find the DynamoDB schema in the docs at

    Getting Started

    1. Install next-auth and @next-auth/dynamodb-adapter
    npm install next-auth @next-auth/dynamodb-adapter
    1. Add this adapter to your pages/api/[...nextauth].js next-auth configuration object.

    You need to pass DocumentClient instance from aws-sdk to the adapter. The default table name is next-auth, but you can customise that by passing { tableName: 'your-table-name' } as the second parameter in the adapter.

    import { DynamoDB } from "@aws-sdk/client-dynamodb"
    import { DynamoDBDocument } from "@aws-sdk/lib-dynamodb"
    import NextAuth from "next-auth";
    import Providers from "next-auth/providers";
    import { DynamoDBAdapter } from "@next-auth/dynamodb-adapter"
    const config: DynamoDBClientConfig = {
      credentials: {
        accessKeyId: process.env.NEXT_AUTH_AWS_ACCESS_KEY as string,
        secretAccessKey: process.env.NEXT_AUTH_AWS_SECRET_KEY as string,
      region: process.env.NEXT_AUTH_AWS_REGION,
    const client = DynamoDBDocument.from(new DynamoDB(config), {
      marshallOptions: {
        convertEmptyValues: true,
        removeUndefinedValues: true,
        convertClassInstanceToMap: true,
    export default NextAuth({
      // Configure one or more authentication providers
      providers: [
          clientId: process.env.GITHUB_ID,
          clientSecret: process.env.GITHUB_SECRET,
          server: process.env.EMAIL_SERVER,
          from: process.env.EMAIL_FROM,
        // ...add more providers here
      adapter: DynamoDBAdapter(

    (AWS secrets start with NEXT_AUTH_ in order to not conflict with Vercel's reserved environment variables.)

    Table structure

    The table respects the single table design pattern. This has many advantages:

    • Only one table to manage, monitor and provision.
    • Querying relations is faster than with multi-table schemas (for eg. retreiving all sessions for a user).
    • Only one table needs to be replicated, if you want to go multi-region.

    Here is a schema of the table :
