KDE Keysmith
Berlin, Germany
What it is
KDE Keysmith is a free, open-source Linux desktop application that generates one-time passwords for two-factor logins. It supports both time-based one-time passwords, known as TOTP, and hash-based one-time passwords, known as HOTP. KDE lists installation through Discover, AppStream application stores, distribution package managers, and Flathub, and the app can work offline. Keysmith is licensed under GPL-3.0-or-later, with KDE listed as its publisher. Features added in a 2021 release include basic account-issuer settings, advanced HOTP and TOTP token configuration, and parsing of otpauth:// addresses, including command-line acceptance. KDE provides links to a forum, bug-reporting page, and source repository. The listed deployment is desktop Linux, although Flathub describes the app for Plasma Mobile and Desktop. No mobile app, push approval, encrypted backup, or team administration is listed. The product facts also name BibTeX, RIS, and ISI as import formats without explaining their role in authentication.
For and against
For
- Supports TOTP and HOTP codes
- Works offline
- Free and open source
- Linux installation through multiple channels
- Accepts otpauth:// URI imports
Against
- No push approvals
- No encrypted backup
- No team administration
- No mobile app listed
The verdict
Keysmith focuses on straightforward one-time-code generation for Linux desktops. Its offline operation and open-source license are useful for individual users, but the listed feature set omits mobile and team-oriented capabilities.
Who it suits
Keysmith suits individual Linux desktop users who want offline TOTP and HOTP code generation in free, open-source software. It is less suitable for teams or users requiring mobile access and centralized account features.
