Hi everyone,

Face Id feature is a new trend in the smartphone world. I was thinking is there a mobile wallet that can use face id instead of 12 words seed?

Basically, I would like to have something like this:

The wallet app scans the face and extracts its id
Then it uses this id to generate an appropriate seed
Finally the wallet derives the keys from the seed as usual

So, as you can see, it would be very convenient to restore the bitcoin wallet just by using your face.

Hope all this makes sense.

Hi, I can understand why you'd like to have this kind of wallet - it's convenient. But please, make yourself familiar with the importance of security in regard to cryptocurrencies. Once compromised a wallet/address is compromised forever, you can't undo it and the worst is, you aren't even aware that it is compromised until it's too late.

Your idea has a flaw too. What happens if I scan your face with face ID? Will it generate the same seed you got? If not, how is it then a unique key/seed?
I know that your idea is basic and just an idea, but as long as the technology isn't there, this will most likely stay an idea

I don't want to come across as rude but I can't help it, I must post this link for you Wink

If the answer isn't yes >> don't use it for crypto
