What is a Login Issue?
A login issue, such as an incorrect username or password, occurs when the user enters the wrong information to access their account. In this case, we're focusing on usernames.
The Role of Usernames in Number Fields
Usernames are unique identifiers for each user within a number field. They serve as keys to encrypt and decrypt user-specific data. However, if an incorrect username is entered, the decryption process fails, leading to a login issue.
Understanding the Problem with Incorrect Usernames
When an incorrect username is used, the decryption algorithm attempts to find a matching key. If no match is found, the encryption algorithm returns an error message, indicating that the login attempt was unsuccessful.
