Copper - Password-free signups. No social network required.

I used to work at an SSO/Password Manager company and wow, I love this solution!! How will you handle spoof'ed numbers? What apps are using you already, and how will developers respond to the risk of using a new startup to do their authentication? (esp. in this fundraising climate?)

Pleasantly surprised to see it working with a foreign mobile number!

Looks like Copper is dead. Website displays an error message stating there's no Heroku app hosted at the domain.

server not found...

Is this dead?

Did not work with my Indian Number. Plus Digits by Fabric does something like this already. Whats better in your case..? BTW Loved the placement of emojis :)

Yep. I love this.

How do you see the implications of this product for lets say, FinTech apps, where security is a primary concern?? Sign ups have always been a big conversion blocker...

I am getting stuck on the continuing confirmation step. Will try again in a couple of hours. Very excited at the prospect.

I could see this working on a few projects but not all. I am curious on the statistics on what users prefer. Social vs Phone numbers. I am always hesitant to give out my phone number.
