🧑💻 Authentication
- Defines: Who you are
- Purpose: Verify identity
- Happens: Before authorization
-
Examples:
- 🔑 Entering username & password
- 📲 Logging in with Google
- 🔍 Scanning fingerprint
🛂 Authorization
- Defines: What you can do
- Purpose: Control access
- Happens: After authentication
-
Examples:
- ✅ Access to admin dashboard
- 🚫 Restricting users from editing content
- 📂 Viewing certain files
💡 Think of It Like This
🏛️ Authentication = Showing your ID at the door
🚪 Authorization = Which rooms you're allowed to enter
✅ Both work together to keep apps and data secure.
Without one, the other can't function effectively.
