This repository contains multiple examples of how to implement BankID authentication in different programming languages and frameworks. The goal is to provide simple, self-contained authentication flows following BankID's official guidelines and best practices.
Each example includes:
- A basic authentication flow
- A simple JWT token issued after successful authentication
- A separate implementation per language/framework
- Full support for BankID test environment
| Language / Framework | Path / Folder |
|---|---|
| ✅ Next.js | /nextjs |
| 🚧 React & Node.js | (coming soon) |
| 🚧 C++ | (coming soon) |
| 🚧 C# | (coming soon) |
| 🚧 Rust | (coming soon) |
| 🚧 Python | (coming soon) |
| 🚧 Go | (coming soon) |
- Compliant with BankID's technical requirements and flow (Auth → Collect → Completion).
- Designed for learning and quick prototyping.
- Stateless JWT-based session handling.
- Easy to extend into production systems.
All examples in this repository use BankID test certificates. These are only valid for development and testing purposes in BankID’s test environment.
- You must acquire production certificates from BankID via your integration partner or BankID directly.
- Never commit certificates or sensitive data to version control.
- Certificates should be securely loaded via environment variables or secure configuration tools.
- Make sure
.gitignoreincludes all sensitive.pem,.p12, and.crtfiles used locally.
Example .env variables:
BANKID_CLIENT_CERT=path/to/client.pem
BANKID_CLIENT_KEY=path/to/key.pem
BANKID_CA_CERT=path/to/ca.pemFeel free to contribute with examples in more languages (e.g. Python, Go, Rust, C++) or improvements to existing ones. Please ensure your implementation matches the BankID flow and includes certificate management, proper error handling, and basic JWT session handling.
