Google Authenticator, Microsoft Authenticator, and Authy are out, because this open-source app replaced them all

When it comes to authenticator apps, I’ve tried a few: Microsoft Authenticator, Authy, and Google Authenticator. Each served its purpose, but they either locked you into proprietary ecosystems or made moving between devices tricky. Then I found 2FAS, a free, open-source solution that offers more control without sacrificing convenience.
