They’re also the backbone of modern two-factor authentication. - With <code>totp</code> I hope to make - handling <abbr class="totp">TOTP</abbr> codes as easy and extensible as - possible. - </p> - - <h2 id="terms">Terminology</h2> - <p> - There are a few terms that I will be using throughout this post, so it’s - good to make sure that we’re all on the same page about what I’m - referring to. - </p> - - <dl> - <dt>Secret</dt> - <dd> - <p> - Your <em>secret</em> is - a <a href="https://en.wikipedia.org/wiki/Base32" - target="_blank">base32</a> encoded secret key that you should under - no circumstances share with anyone else.

We can extract - these from downloaded images using utilities such - as <code>zbarimg</code> and use them in <code>totp</code> using - the <code>-u</code> flag to enable ‘<abbr class="uri">URI</abbr> mode’ - </p> - - <figure> - <pre>m4_fmt_code(zbarimg.sh.html)</pre> - </figure> - - …and that’s all! There’s nothing else you need. You can use secret keys - and otpauth <abbr class="uri">URI</abbr>s, and you can configure - the <em>digits</em> and <em>period</em> of the generated codes. You can - generate multiple keys at once, and all outputs are printed to the - standard output. - </main> - - <hr> - - <footer> - m4_footer - </footer> - </body> -</html> |
