Java Program to Demonstrate How User Authentication is Done
Authentication is the process of verifying the identity of users or information. User authentication is the process of verifying the identity of the user when that user logs in to a computer system. The main objective of authentication is to allow authorized users to access the computer and to deny access to unauthorized users.
Default Assumption: User name = Geeks For Geeks , Password = Geeks For Geeks Input: User name = Geeks For Geeks, Password = Geeks For Geeks Output: Authentication Successful Input: User name = Geeks For Geeks, Password = Hello world Output: User name/ Password not matching
- Take username and password as string input from the user.
- Check if the username matches the password or not.
- If it matches then welcome the user.
- Else display an appropriate message.
Below is the implementation of the above approach
