Suggested Improvements:

• Use bcrypt to hash and compare passwords securely.

Storing plain text passwords is a major security risk. You should hash the password before storing it in the database.

• Standardize error handling to provide more meaningful responses.

• Omit sensitive data (like passwords) from the response.

Password and other sensitive data should not be included in any response.

• Use JWT for authentication to handle login tokens.
