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

neatly done worked for me & :thumbsup: for international phone number support !!

Beautifully designed, simple and useful => I think you're on the right track guys! Would just add the option to receive the code with email when your phone's battery is dead

Cool idea! You got some front-end bugs to fix - look poor

Are y'all thinking about integrations with other software companies that require access to user accounts? Or how would that work with Copper?

What about pricing? And model?

how is this different than Facebook's account kit? http://venturebeat.com/2016/04/1...

only for USA customers?

Looks cool! I guess the issue with international numbers is still there. Didn't receive the signup code on an Indian number.

Great idea. Passwords drive me insane.

Considering GSMA's Mobile Connect's launch, this is bad timing for this. But better a startup then some telecom coalition, eh?
