Features

• User registration with and without email verification
• Email format validation
• Secure password hashing with bcrypt
• User login/authentication
• Password reset via email verification
• MongoDB-based user data persistence
• Saving custom per user data
• User blocking functionality
• Email change with or without verification

Usage

from easy_mongodb_auth_handler import Auth

auth = Auth(
    mongo_uri="mongodb://localhost:27017",
    db_name="mydb",
    mail_info={
        "server": "smtp.example.com",
        "port": 587,
        "username": "[e-mail]",
        "password": "your_email_password"
    }, # Optional: Include if using email verification
    blocking=True/False,  # Optional: True to enable user blocking
    readable_errors=True/False,  # Optional: False to switch to numeric error codes translated in the README.md file
    attempts=6,  # Optional: Number of attempts for initial MongoDB connection (default is 6).
    delay=10,  # Optional: Delay in seconds between MongoDB initial connection attempts (default is 10 seconds).
    timeout=5000,  # Optional: Timeout in ms for MongoDB connection (default is 5000 ms).
    certs=certifi.where()  # Optional: Path to CA bundle for SSL verification (default is certifi's CA bundle)
)

This code initializes the package. The mail arguments are not required, but needed to use verification code functionality. The blocking argument is optional and defaults to True. If set to True, it enables user blocking functionality. All methods return True or False with additional detailed outcome reports.

Function Reference - auth.example_func(args)

All functions return a dictionary: {"success": True/False, "message": "specific message"}.

Return code translation

These codes are returned by the functions in the package if readable_errors is set to False. Error codes starting with 2xx indicate success, while those starting with 4xx indicate errors. 3xx codes indicate user status checks. 5xx codes indicate authentication errors.
