User Authentication in Low Level Design (LLD)
Here are the steps involved in planning or designing the authentication process:
Below is the explanation of the steps mentioned above:
- Authentication Section: Create a special part of the system just for checking if users are who they say they are.
- User Information: Decide where and how the software will keep things like usernames and passwords.
- Password Safety: Figure out how to keep passwords safe using special techniques.
- Login Management: Plan how the software will handle users logging in, including how long they can stay logged in.
- Extra Security Steps: Decide how to include extra security layers, like using a code sent to a user’s phone.
- Dealing with Mistakes: Plan what happens if someone tries to log in and makes a mistake, like limiting their attempts.
- Special Cases: If users forget their passwords, design a secure way for them to reset it.
- Connecting to Other Systems: If your system needs to work with other systems for login, decide how they will talk to each other.
- Protecting Against Attacks: Plan how to stop different types of attacks, like someone trying lots of passwords.
- Testing Everything: Create tests to make sure the login system works correctly and is secure.
Difference between Authentication and Authorization in LLD | System Design
When building computer programs, especially when designing complex systems, it’s super important to understand two key things: authentication and authorization. Even though these words sound similar, they do different jobs to keep our systems safe.
