I'm thinking about building a service which is capable of receiving your 2FA SMS texts from third parties, and forwarding them to you via email.

We'd do this by registering numbers on your behalf, which you'd then use when signing up for the third-party (or setting up 2FA later).

This has a number of advantages:

• SMS can be unreliable and/or slow
• your phone might not be nearby, charged, or have signal
• you could share the codes with other trusted contacts (via email, or have their own accounts to view online)
• can use auto-generated numbers to reduce risk (multiple numbers, multiple services)
• "new phone who dis?" no probs, your number isn't bound to any of those services any more

There would be an option to forward directly via email and/or to view the latest code(s) on the site.

I can see this being especially useful for SMEs where a lot of 'personal' SaaS plans are being used—where there's often only a single root user which multiple people access—or individuals who dislike being bound to a phone number.

I will never have enough information to access their account for the 3rd party service, and I'll only be processing the codes. Privacy & security is my primary concern with this, I am not interested in holding the keys to anyone's castles, so I will be operating on a minimum trust basis.

Really keen to get some thoughts on this project. If I go ahead with it, I'm intending to build it as an Open Startup and share progress in public.
