YKOATH-RS is a simple GTK indicator applet that lists any YubiKeys that are detected and allows you to view TOTP codes for 2 factor authentication and click to copy to clipboard.
Disclaimer: I wrote this for myself, because the
yubioath-desktopapplication did not suit my needs and I'm also learning Rust. Merge requests are very welcome, but this is a hobby project that I am pretty unlikely to consistently support and maintain.
cargo install ykoath

There's also a small library exposed if you need it.
