  1. Actually text me the one-time passcode, rather than saying you sent it to me while instead texting it to the molten core of the earth.

Uhhh… how about NO??

In fact, as a casual security professional (it’s not a core part of my job, but I know a lot more than most ppl), I openly advocate making SMS and eMail illegal for transmitting one-time passcodes.

Why? Because both are critically insecure, cannot be adequately secured outside of laboratory or highly restrictive environments, and can be trivially hijacked.

The only one-time passcode that should be used are one-time password generators (TOTP) such as Google Authenticator or any other such method.

Yes, this requires a little more effort on the part of the site owner, but it’s worlds better than SMS or eMail, and far more user-friendly than forcing the user to open the company’s app just to receive the code (looking at you, Canadian banks and other businesses like Telus).
