A TOTP1 based 2FA system has two parts. One is a client that generates the TOTP code. The other part is a server. The server verifies the code. If the client and the server-generated codes match, the server allows the inbound user to access the target system. The code usually exp...

I love Go’s implicit interfaces. While convenient, they can also introduce subtle bugs unless you’re careful. Types expected to conform to certain interfaces can fluidly add or remove methods. The compiler will only complain if an identifier anticipates an interface,...
