There are more ways to utilize OTP then to 2FA accounts.

Using an offline otp manager like andOTP you can generate time based codes derived from any shared secret. This can provide a whole new level of security in a scenario where Alice and Bob want to self verify a communication channel.

This is a community for enthusiest who love to ponder new ways for Alice to communicate with Bob in a world where global passive adversarys probably record every bit that ever crosses the wire.

Discuss cryptography, secure key exchange, private messangers, radios, encoding, networking tools, authentication mechanisms and anything relevant to coming up for ways to Alice to get a message to Bob.
