I like the idea!

I would suggest an encrypted backup/import procedure.

I like this. I’ll think about it

Mobile app is not available on stores yet. Source code is open source https://github.com/zerologin/zerologin-mobile You can build it yourself if you want to try it

For those of us coming from Multi seed backup phrase wallets like Metamask, this comes easy to understand.

I’m lost

It’s ok, what you don’t understand?

So you create new seeds everytime you login?

No of course. 1 seed enough majority of people. But this app allow you to add as much as you want, in case you need it (ex: you want multiples accounts on lnmarkets)
