What is two-factor authentication (2FA)?
2FA adds a second step to the login process, in addition to your traditional password.
After entering your password, you must also provide a unique code generated by a 2FA app on your smartphone.
This extra step makes it much more difficult for hackers to access your account, even if they know your password.
Google Authenticator: Simple and effective
Google Authenticator is a free and open source application developed by Google.
It is easy to set up and use. Simply download the application on your smartphone, scan the QR code provided by your online account and that's it! The app will generate unique codes that you must enter when you log in.
Advantages:
- Simple and easy to use: The application has an intuitive and easy-to-use interface.
- Free and open source: Google Authenticator is completely free and its code is available so anyone can verify its security.
- Wide Compatibility: The application is compatible with various online services, including Google, Facebook, Twitter, Dropbox and many others.
- Examples of use: Imagine you are logging into your Facebook account. After entering your password, Google Authenticator will automatically open and generate a unique code. You must enter this code into Facebook to complete the login process. This ensures that even if someone has your password, they won't be able to access your account without the Google Authenticator code.
Disadvantages:
- No cloud backups: If you lose your smartphone, you will also lose the 2FA codes.
- No cross-platform support: The application is only available for Android and iOS.
- Basic interface: The design of the app is simple and may look a little dated.

Authy is another popular 2FA app that offers some additional features compared to Google Authenticator.
In addition to generating 2FA codes, Authy also allows:
- Cloud backups: Back up your 2FA codes to the cloud so you can restore them in case you lose your smartphone.
- Synchronization between devices: Access your 2FA codes on all your devices, even if you don't have your main smartphone with you.
- Cross-platform support: Authy is available for Android, iOS, Windows, macOS and Linux.

- Hardware tokens: Use physical hardware tokens to generate 2FA codes, for greater security.
Advantages:
- Advanced Features: Cloud backups, cross-device syncing, cross-platform support, desktop app, biometric authentication, and hardware token support.

- Premium version: The premium version of Authy offers additional features such as biometric authentication and hardware token support.
- Examples of use: Imagine you are logging into your Twitter account. You can use the Authy app on your smartphone to generate a unique code. Next, enter this code into Twitter to complete the login process. Authy also offers the option to use biometric authentication to unlock the app and access your 2FA codes, making the process even faster and more secure.
Disadvantages:
Limited free version: The free version of Authy limits the number of devices you can sync.
It is not open source: Authy's code is not open to the public, which means not everyone can verify its security.
