Authentication for single-page applications using the Angular framework and Play Framework in the Java programming language

I'm seeking guidance on how to design an authentication mechanism using Angular front-end and Play Framework (Java) back-end. Here's the basic concept:

  1. Angular sends a REST authentication call to the Play Framework.
  2. Play generates a token and sends it back to Angular.
  3. Angular uses the token to make subsequent REST calls.

Ideally, I'd like to incorporate CSRF token into the process. However, I've struggled to find comprehensive resources on integrating Angular and Play authentication. While there are plenty of guides for JavaScript and Play integration, my scenario is quite unique.

My question is focused on how to approach the design, which frameworks/functionality to utilize, and how to effectively integrate Angular and Play in this context. General steps for achieving this objective would be appreciated, such as implementing an authentication framework in Play, integrating relevant functionality, utilizing methods in Angular, and ensuring seamless connectivity. Specific instructions or tips on securely storing password hashes in the database using Play mechanisms or other frameworks would also be valuable.

Answer №1

If you're looking to secure your Angular app, consider using technologies like JSON Web Tokens (JWT) to create and manage authentication tokens. The process typically involves:

  • User provides login credentials (e.g., email and password);
  • Play verifies the information provided, generates a token containing user permissions/roles, creation date, etc., if everything checks out;
  • Once you have the token, integrate it into your Angular app. Play will need to validate the token to ensure its authenticity and expiration status.

To enhance security measures, consider storing these tokens in a database for functionalities such as blacklist management or automated token renewal. Alternatively, you can generate custom tokens (e.g., base64 strings) with associated data stored in a database, or utilize Play cookies (not directly accessible by Angular due to HTTP-only restrictions).

When it comes to password hashing, prioritize security by selecting reliable Scala/Java libraries. Popular options include BCrypt, scrypt, pbkdf2, among others available on market.
