Description
OAuth 2.0 allows applications to access users' resources without exposing their credentials. It is a flexible and secure method employed in many modern web applications.
✔Benefits
- Increased security through access controls.
- Simplified user login.
- Enhanced integration capabilities.
✖Limitations
- Complexity in implementation.
- Access rights are difficult to manage.
- Potential issues with token expirations.
Trade-offs
Metrics
- Number of Successful Authentications
Measures how often users successfully access the system.
- Token Expiration Time
Indicates the duration until a token expires.
- Access Requests per Hour
Measures the load on the system.
Examples & implementations
OAuth 2.0 in Google API
Google uses OAuth 2.0 for authorizing API access.
Facebook Login
Facebook allows authentications via OAuth 2.0.
GitHub OAuth
GitHub allows users to access accounts via OAuth 2.0.
Implementation steps
1
Define the use cases.
2
Integrate OAuth libraries into the project.
3
Test authentication mechanisms.
⚠️ Technical debt & bottlenecks
Technical debt
- Using outdated libraries.
- Missing authentication logic.
- Weak token management practices.
Known bottlenecks
Token ManagementUser ManagementAPI Documentation
Misuse examples
- Transmit tokens without encryption.
- Store user data insecurely.
- Not implementing token management.
Typical traps
- Ignoring technical debts.
- Not performing enough tests.
- Inadequate documentation.
