Automatic selection of slot 1 can be inconvenient.

Recent reviews

Does exactly it's supposed to. Importantly makes Kerpass2Android Yubikey capable.

Works perfectly! Saved a huge amount of time in trying to understand the Android Yubikey example. Update August 2024: continuing to be pleased with the support this (now invisible!) app offers to my own apps which use the challenge-response protocol of the Yubikey. Works perfectly and easy to use.
