- 3. What to expectfrom this session? • High-level overview of AWS Mobile Services • Deep dive into Amazon Cognito, specifically Cognito User Pools • Walkthrough of a ready-to-use Angular 2 app powered by Cognito • How to store & manage users without creating a line of server-side code (no plumbing needed!)
- 4.

- 6. AWS Mobile SDKs Authenticateusers Analyze User Behavior Store and share media Synchronize data Deliver media Amazon Cognito (Sync) Amazon Cognito (Identity) Amazon S3 Amazon CloudFront Store data Amazon DynamoDB Track Retention Amazon Mobile Analytics Send push notifications Amazon SNS Mobile Push Server-side logic Lambda Device Farm Test your app Build and Scale Your Apps on AWS Amazon Mobile Analytics
- 7. What is AmazonDynamoDB? • Managed NoSQL database service • Consistent, low latency performance (single digit ms) at any scale • Predictable provisioned throughput • High durability and availability (3x replication) DynamoDB
- 8. What is AmazonS3? • Cloud storage • Static website hosting • 11 9’s of Durability • 4 9’s of Availability • CloudFront Integration
- 9. Undifferentiated Heavy Liftingof Authentication • Create and secure a database • Create the UI • Create the server-side code • Create the IdP access token verification logic • Consolidate IdP credentials • Generate and manage a custom secure token • Manage the token lifespan • Manage the user lifecycle
- 10.
- 11. Manage authenticated and guestusers’ access to your AWS resources Federated Identities Synchronize user’s data across devices and platforms via the cloud Data Synchronization Add sign-up and sign- in with a fully managed user directory Your User Pool GuestYour own auth Amazon Cognito Identity Amazon Cognito Sync k/v data What’s Amazon Cognito?
- 12. Amazon Cognito FederatedIdentities • Authenticate Users with third-party IdPs • Authenticate with Cognito User Pool • Anonymous Identities • Federation of Identities • OpenID Connect Token Generation • Control access from your app to other AWS Services
- 13. Amazon Cognito Sync •Store Customer Data in the Cloud • Synchronize Data • Cognito Events Trigger AWS Lambda Functions • Cognito Streams Send Data to Amazon Kinesis
- 14. Amazon Cognito UserPools Add sign-up and sign-in easily to your mobile and web apps Easy User Management Verify phone numbers and email addresses and offer multi-factor authentication Enhanced Security Features Launch a simple, secure, low-cost, and fully managed service to create and maintain a user directory that scales to 100s of millions of users Managed User Directory
- 15. Comprehensive User Scenarios Emailor phone number Verification Forgot Password User sign-up and sign- in Users verify their email address or phone number prior to activating an account Users can change their password if they forget it Users sign-up using email, phone number or user name and password. Users can then sign-in. User Profile Retrieve and update user profiles, including custom attributes SMS-based MFA If enabled, users complete Multi-Factor Authentication (MFA) with a confirmation code via SMS as part of sign-in and forgot password flows
- 16. Customization using Lambdahooks Lambda Hook Example Scenarios Pre user sign-up Custom validation to accept or deny the sign-up request Custom message Advanced customization and localization of verification messages Pre user sign-in Custom validation to accept or deny the sign-in request Post user sign-in Event logging for custom analytics Post user confirmation Custom welcome messages or event logging for custom analytics
- 17. Comprehensive Administrator Scenarios Manageusers in a User Pool Select Email and Phone Verification Customize with Lambda Triggers Setup Password Policies Create and manage User Pools List, search and perform actions on specific user(s) in the User Pool Configure verifications of users’ email addresses and phone numbers (via SMS) Create functions in AWS Lambda to customize workflows Control password requirements like minimum length, uppercase, and inclusion of special characters Create, configure and delete multiple User Pools in their AWS account Define Attributes Select required attributes and Define custom user attributes
- 18. Secure Sign-in MadeEasy Token-based Authentication Secure Remote Password Protocol SMS-based Multi-factor Authentication Uses tokens based on OpenID Connect (OIDC) and OAuth 2.0 standards Uses Secure Remote Password (SRP) for secure password handling end to end Enables your end users to use the text messaging functionality of a mobile phone as an extra layer of security

- 21. Authentication Flow Amazon Cognito UserPools Amazon DynamoDB Mobile apps Lets walk through this step by step…S3 Lambda Hooks Amazon Cognito Identities
- 22. Authentication Flow Amazon Cognito UserPools Amazon DynamoDB Mobile apps Step 0: User invokes the website hosted on S3 Amazon S3 can be used as a highly available website hosting platform Lambda Hooks Amazon Cognito Identities S3
- 23. Authentication Flow Amazon Cognito UserPools Mobile apps Step 1: User signs up for an account with our Amazon Cognito User Pool, providing their email & password (+ any custom attributes). Amazon Cognito can automatically verify the user’s email address and/or phone number if required. S3 Amazon DynamoDB Lambda Hooks Amazon Cognito Identities
- 24. Authentication Flow Amazon Cognito UserPools Mobile apps Step 2: At some point in the future, the user wants to sign in. We can now authenticate the user. Amazon DynamoDB Lambda Hooks Amazon Cognito Identities S3
- 25. Authentication Flow Amazon Cognito UserPools Mobile apps Optional: If MFA is enabled (either for this user, or all users), Amazon Cognito will SMS a one time authentication code to the user. Amazon DynamoDB Lambda Hooks Amazon Cognito Identities S3
- 26. Authentication Flow Amazon Cognito UserPools Mobile apps Optional: If Lambda Hooks are setup, then they will be invoked Amazon DynamoDB Lambda Hooks S3 Amazon Cognito Identities
- 27. Authentication Flow Amazon Cognito UserPools Mobile apps Step 3: After a successful authentication, Amazon Cognito responds with a signed JSON Web Token (JWT) containing the user’s details. Amazon DynamoDB Lambda Hooks S3 Amazon Cognito Identities
- 28. Authentication Flow Amazon Cognito UserPools Mobile apps Step 4: Once you’re authenticated, you want to retrieve your scoped AWS credentials to access other services. Amazon DynamoDB Lambda Hooks S3 Amazon Cognito Identities
- 29. Authentication Flow Amazon Cognito UserPools Mobile apps Step 5: You are now ready to call DynamoDB. Amazon DynamoDB Lambda Hooks S3 Amazon Cognito Identities
- 30. Going serverless Amazon Cognito UserPools Amazon API Gateway Lambda Hooks /v1 Lambda Function /v2… Lambda Function Amazon DynamoDB Throttling Cache Logging Monitoring Auth Mobile apps This is a more complete solution that you can achieve without managing servers… S3 Amazon Cognito Identities
- 31. Getting started withthe QuickStart app
- 32. Tech Stack • RequiredTools • aws cli • npm • bower • angular-cli • Frameworks • AWS JavaScript SDK & Amazon Cognito Libraries • Angular 2 (Ionic) RC2 • TypeScript • Bootstrap

- 36. Types • ID Token •JWT • OpenID Identity Information (name, phone_number, etc) • Access Token • JWT • No Identity Information • Used for further authorizations • Refresh Token • String • Refresh Amazon Cognito Identity session
- 37. ID Token • Header •kid – used to locate the public key • alg – RS256 • Payload • user attributes (user identity information) • iss – the issuer • sub – UUID of the authenticated user • token_use – the purpose of the token • Signature • Based on header and payload
- 38. Access Token • Header •kid – different from ID token since different keys used • alg – RS256 • Payload • username – (e.g. vladimir@budilov.com) • Signature • Based on header and payload
