Authenticator for Linux

Authenticator is a Linux app designed to create two-factor authentication (2FA) codes.

It helps improve account security by generating one-time passwords (OTP) using several methods and algorithms.

This software fits well for users running Linux who want a reliable tool to manage their authentication codes.

The app supports multiple algorithms, including SHA-1, SHA-256, and SHA-512.

These options provide flexibility and compatibility with various online services that require two-factor codes.

Authenticator can generate codes based on time (TOTP) or counters (HOTP) and even supports the Steam method, making it useful across different platforms that use 2FA.

One notable feature is its QR code scanner, which works with your camera or can scan from a screenshot.

This makes adding new accounts quick and easy without manually entering long keys.

The app also offers a password lock to add an extra layer of security when you use it.

Authenticator allows you to back up and restore your codes from popular apps like FreeOTP+, Aegis, and Google Authenticator.

This helps users switch devices or recover their accounts without losing important 2FA data.

However, it is not clear if the app works on platforms other than Linux, and it does not mention syncing across multiple devices.

The software uses GTK and integrates smoothly with the GNOME desktop environment, including search functions through GNOME Shell.

Overall, Authenticator provides a straightforward way for Linux users to safely generate and manage their 2FA codes.
