Why Authenticator Apps Are Safer Than SMS for Login Security

INTRODUCTION
One of the best ways to add extra security to your accounts is through Multi-Factor Authentication (MFA) – this means you need more than just a user ID and password to log in. We strongly recommend using MFA for your important accounts.
However, not all MFA methods are equally secure. Authenticator apps are a safer option than SMS authentication methods because they generate security codes directly on your device. SMS authentication codes, on the other hand, can be intercepted by hackers.
WHAT IS MULTI-FACTOR AUTHENTICATION AND WHAT IS THE BENEFIT?
MFA adds an extra step to logging in. Instead of just entering a user ID and password, you must also provide another piece of information, like a code from an app or a text message. This extra step makes it much harder for hackers to break into your account, even if they steal your password.
MFA METHOD #1: WHAT IS AN AUTHENTICATOR APPLICATION?
An authenticator app is a mobile app that generates security codes for logging in. These codes are called Time-Based One-Time Passwords (TOTP) and change every 30 to 60 seconds.
When you set up an authenticator app for an account, you scan a QR code or enter a secret key. This links the authenticator app to your account and allows it to generate matching codes.
To log in, you enter your username, password, and the current code displayed on your authenticator app. If the code matches the one your account server expects, you get access.
Some popular authenticator applications include:
- Google Authenticator
- Microsoft Authenticator
- Authy
- Duo Mobile
MFA METHOD#2: WHAT IS SMS AUTHENTICATION?
SMS authentication is when a security code is sent to your phone via text message. You enter this code along with your user ID and password to log in. These codes are One-Time Passwords (OTP) which are generated for one-time use. OTPs can last for a specified amount of time – users will need to generate a new OTP if they exceed the time limit.
Sometimes, websites may also send security codes via email instead of SMS, but the process is the same.
WHY AUTHENTICATOR APPLICATIONS ARE PREFERRED OVER SMS AUTHENTICATION
Authenticator apps provide better security than SMS codes for several reasons:
- Less chance of being hacked: Authenticator apps generate codes directly on your device, while SMS codes are sent over the internet and can be stolen.
- No risk of SIM swapping: Hackers can trick your phone provider into transferring your number to a new SIM card, allowing them to receive your SMS codes.
- No risk of interception: SMS codes can be stolen using man-in-the-middle attacks, where hackers eavesdrop on internet traffic.
- Codes change frequently: Authenticator apps refresh their codes every 30 to 60 seconds, making them harder to steal and use.
HOW HACKERS CAN STEAL SMS CODES
Here are two common ways cybercriminals can steal SMS codes:
- Man-in-the-Middle Attacks – Hackers intercept your internet traffic when you connect to an unprotected Wi-Fi network (like public Wi-Fi at a coffee shop). This can let them steal SMS codes.
- SIM Swapping – A hacker contacts your mobile provider pretending to be you and tricks them into activating a new SIM card with your phone number. Now, they receive all your text messages, including your security codes.
HOW TO KEEP YOUR ACCOUNTS SAFE
- Use an authenticator app instead of SMS authentication whenever possible.
- Protect your phone with a strong PIN or password.
- Avoid using public Wi-Fi when entering security codes.
- Never share your security codes with anyone.
- Be cautious of phishing scams that try to trick you into revealing your codes.

Toyota Confirms Ransomware Attack, Data Breach
Introduction
Toyota Finance Services (TFS), a subsidiary of the well-known automaker, has confirmed that they were hit with a ransomware attack. TFS detected unauthorized access to some of its systems in Africa and Europe after cybercriminals claimed an attack on the company. The cybercriminals, also known as the Medusa ransomware gang, claims responsibility for the attack.
Summary Of the Incident
The Medusa ransomware gang had listed ‘Toyota Financial Services’ to its data leak site on the dark web and demanded a ransom payment of $8,000,000 to delete allegedly stolen data. The cybercriminals published sample data that included financial documents, hashed account passwords, passport scans, etc. to prove the intrusion. As of right now, the incident is limited to Toyota Financial Services Africa & Europe. A spokesperson announced that the process of bringing their systems back online is already underway.
How to Stay Safe
- Reset All Passwords – If you are reusing passwords across different websites, reset those passwords and employ hard-to-guess, complex passwords on those websites.
- Password Manager – To keep track of your complicated passwords, think about investing in a password manager. Password managers, like 1Password, place a secret key on your password manager to add a unique extra layer of security.

Using AI Tools Securely: ChatGPT, Gemini, and More
INTRODUCTION
AI-powered tools are now integrated into various platforms, from office software and operating systems to image editors and chat applications. But how can you use ChatGPT, Gemini, DeepSeek, and other AI-powered tools without compromising your digital security?
AVOID SHARING SENSITIVE INFORMATION WITH AI CHATBOTS
OpenAI’s privacy policy indicates that user data may be utilized to enhance AI performance. When using services like ChatGPT, Sora, or Operator, your interactions could be used to train AI models.
According to a study done by Harmonic Security, 8.5% of prompts contained sensitive information.
Never input sensitive personal information such as passwords, passport or banking details, addresses, phone numbers, names, or any confidential business data. If necessary, replace sensitive details with placeholders like asterisks or “REDACTED.”
For professionals, especially software engineers leveraging AI for code review, it’s crucial to strip out any information that could reveal company secrets and/or application structure.
Everything shared with an AI chatbot has the potential to be stored and analyzed.
FREE AI SERVICES COME WITH HIGHER RISKS
Many free-tier AI tools explicitly state that they train on user data. Organizations using AI should consider investing in paid AI services like ChatGPT Enterprise, which ensures that user inputs and outputs are not utilized for training purposes.
Experts recommend paid plans as a more secure option for businesses looking to mitigate risks.
BEST PRACTICES FOR SAFE AI USE IN THE WORKPLACE
For businesses looking to integrate generative AI tools while minimizing security risks, Harmonic Security suggests shifting away from outright bans and instead implementing effective AI governance strategies. These include:
- Establishing clear AI usage policies and enforcing workflows.
- Monitoring AI tool usage in real time to track inputs and ensure compliance.
- Restricting the use of free AI tools that train on input.
- Classifying sensitive data to prevent exposure.
- Educating employees on responsible AI use and associated risks.
