MFAAuthPlus: Extracting TOTP Values, Generating QR Codes, and Using SQLite DB
In this article, we will explore MFAAuthPlus, a tool that has been around for some time and continues to offer unique features. Specifically, we will focus on extracting TOTP (Time-based One-time Password) values and generating QR codes using SQLite database.
What is MFAAuthPlus?
MFAAuthPlus is a multi-factor authentication (MFA) tool that supports various authentication methods, including TOTP. It allows users to generate QR codes, which can be scanned using authentication apps like Google Authenticator, Authy, or Microsoft Authenticator. MFAAuthPlus also supports storing authentication data in a SQLite database.
Extracting TOTP Values
TOTP values are used to generate one-time passwords that are valid for a limited time. MFAAuthPlus allows users to extract TOTP values from the SQLite database using the following SQL query:
SELECT username, secret, label FROM otp\_table;In this query, otp\_table is the name of the table that stores the authentication data. The username, secret, and label columns store the corresponding values for each authentication record.
Generating QR Codes
Once the TOTP values have been extracted, MFAAuthPlus can generate QR codes that can be used to set up authentication apps. The following Python code can be used to generate a QR code:
import qrcode
data = "otpauth://totp/Label?secret=Secret&issuer=Issuer"
qr = qrcode.QRCode(
version=1,
error\_correction=qrcode.constants.ERROR\_CORRECT\_L,
box\_size=10,
border=4,
)
qr.add\_data(data)
qr.make(fit=True)
img = qr.make\_image(fill\_color="black", back\_color="white")
img.save("qr.png")
In this code, the data variable contains the URL that will be used to set up the authentication app. The Label, Secret, and Issuer placeholders should be replaced with the corresponding values from the SQLite database.
Using SQLite DB
MFAAuthPlus supports storing authentication data in a SQLite database. The following SQL commands can be used to create the database and the otp\_table table:
CREATE DATABASE mfa.db;
USE mfa.db;
CREATE TABLE otp\_table (
id INTEGER PRIMARY KEY,
username TEXT NOT NULL,
secret TEXT NOT NULL,
label TEXT NOT NULL,
issuer TEXT NOT NULL
);
Once the database and table have been created, the authentication data can be inserted using the following SQL command:
INSERT INTO otp\_table (username, secret, label, issuer)
VALUES ('username', 'secret', 'label', 'issuer');
In this command, the username, secret, label, and issuer placeholders should be replaced with the corresponding values for the authentication record.
