The bottom line

A convenient desktop authenticator for gamers who accept that it is no longer maintained; everyone else should choose an actively-supported app.

6 - broad game, TOTP and HOTP support and portable, but a stagnant feature set.

8 - free and capable, though the value is offset by being unmaintained.
Ease of use8/10
8 - portable and simple, with no installation required.
Ecosystem5/10

Support2/10
2 - penalized: effectively abandonware, with the maintainer declaring end-of-life.
What it really is

A portable open-source TOTP/HOTP authenticator for Windows - and, in practice, an unmaintained one.

Our take

It still works for storing two-factor codes, including game tokens like Steam Guard and Battle.net, and it keeps everything local. But it is effectively abandonware: no meaningful updates since 2017 and the maintainer has publicly called it end-of-life. Fine if you accept no fixes; risky as your primary authenticator.

Best for
Gamers needing Steam, Battle.net or Guild Wars 2 token support on desktop
Users who want a portable, fully-local Windows authenticator
People comfortable running unmaintained software for the convenience
Not good for
Anyone needing actively maintained, patched security software
Cross-platform users - it is Windows-only
Security-critical setups that depend on ongoing updates
Friction report
Time to value
Immediate: it is portable with no installer and runs from anywhere on Windows 7 through 11.
Scale breakpoint
The limit is maintenance, not scale - with no updates since around 2017, newer authentication schemes or OS-level changes may go unsupported.
Walled garden
Low lock-in: it is open GPLv3 and exportable, though migrating many seeds to a maintained app is a manual job.
