Let's Encrypt features and specs

  • Free of Charge
    Let's Encrypt provides SSL/TLS certificates at no cost, making it an economical choice for individuals and businesses.
  • Automated Certificate Issuance and Renewal
    The process of obtaining and renewing certificates can be automated using the ACME protocol, reducing manual intervention and administrative overhead.
  • Ease of Use
    Let's Encrypt simplifies the process of enabling HTTPS for websites, even for users with limited technical expertise.
  • Security
    Let's Encrypt certificates provide strong encryption, improving the security of data transmitted between clients and servers.
  • Widely Recognized
    Certificates issued by Let's Encrypt are trusted by all major web browsers and operating systems.
  • Promotes Secure Web Practices
    By making SSL/TLS certificates freely available, Let's Encrypt encourages more websites to adopt HTTPS, contributing to a more secure internet.

Possible disadvantages of Let's Encrypt

  • Short Duration of Certificates
    Let's Encrypt certificates are valid for only 90 days, requiring more frequent renewals compared to traditional certificate authorities.
  • Limited Support Options
    Let's Encrypt relies on community support and documentation, and does not offer dedicated customer support for troubleshooting and assistance.
  • No Extended Validation (EV) Certificates
    Let's Encrypt does not issue Extended Validation (EV) certificates, which provide additional verification and a higher level of trust for business websites.
  • Potential for Misuse
    Since certificates are issued for free and with minimal validation, there is a risk that cybercriminals might use them for phishing or other malicious activities.
  • No Wildcard Certificates for Multi-Level Subdomains
    While Let's Encrypt supports wildcard certificates for single-level subdomains, it doesn't support them for nested subdomains (e.g., *.sub.example.com).
  • Reliance on Third-Party Tools for Automation
    Users may need to rely on third-party tools or scripts for automation, which could introduce additional complexity or security risks.

Google Authenticator features and specs

  • Enhanced Security
    Google Authenticator adds an extra layer of security by requiring a second factor of authentication, reducing the risk of unauthorized access even if your password is compromised.
  • Offline Access
    The app does not require an internet connection to generate codes, making it reliable in situations where connectivity is a concern.
  • Compatibility
    Google Authenticator is compatible with a wide range of services and accounts, providing a versatile solution for multi-factor authentication (MFA).
  • Free of Charge
    The application is free to use, offering robust security features without any financial investment.
  • Ease of Use
    Setup and usage are straightforward, making it accessible to users without technical expertise.

Possible disadvantages of Google Authenticator

  • Device Dependence
    If you lose your device, gaining access to your accounts can become challenging, particularly if you haven't backed up or used alternative methods.
  • No Cloud Sync
    Google Authenticator does not offer a built-in feature for cloud backups, making it difficult to transfer codes to a new device.
  • Single Device Limitation
    The app only works on a single device at a time, which can be inconvenient if you manage multiple devices.
  • No Biometric Lock
    The app lacks advanced security features such as biometric locks, which are present in some other authenticator apps.
  • Limited Recovery Options
    In case of losing access to the app, recovery options rely heavily on the user having access to backup codes, which might not always be accessible.

Top 6 Google Authenticator Alternatives in 2023
Although they aren’t as big or widely known as Google or Microsoft, Twilio’s Authy app is one of the most impressive and feature-rich Google Authenticator alternatives. Twilio takes pride in the fact that their app can be used anywhere Google Authenticator can be used, meaning that those making the switch won’t hit any unexpected compatibility issues.
Is Authy better than Google Authenticator?
The difference between Authy and Google Authenticator lies in the number of features offered by each app. If you like minimalism, use Google Authenticator, but if you like multi-device support, full Backup of your 2FA codes, or three authentication types, use Authy.

Google Authenticator is really the baseline here, because nearly all sites that support 2FA support Google’s app as well. For example, LastPass Authenticator and Authy aren’t explicitly supported by as many sites and services. However, they still use TOTP, making them compatible with all services that support Google Authenticator.

  • I'm building a macOS app in a week with Tauri and Supabase.
    Many authenticator apps already exist on Google Play Store and Apple App Store. Most of them have synchronization features but are limited to backup only or sync with the same platform (ie: iOS or Android only). I'm using one of them for years and at this moment I'm feeling bothered when switching to a mobile device every time login into a website or online service. So, I created Otentik Authenticator.
