The six-second signup: one-time codes on the row

Signing up somewhere with an email address costs six steps. Most of them are fetching the code. We lifted it onto the inbox row, and here is why the extractor refuses so much.

Count the steps the next time a site emails you a code: switch to mail, wait, find the message, open it, find the number, select it, copy it, switch back, paste. A phone does it in one tap. Email should too.

What we built

When a code arrives at a Sodaroad address, it appears on the message row itself with a Copy button. It stays there for fifteen minutes and then the row is an ordinary row again. Codes are stored encrypted, because a code is a credential while it lives.

What the extractor refuses

Order numbers, invoice numbers, tracking numbers, account numbers, amounts of money, bare years, and anything ambiguous. A false positive teaches people to stop trusting the feature, and a feature nobody trusts is a feature nobody uses.

The other half, filling the code into the other site, needs a browser extension. It is on the list.
