Hey guys, i want to ask if there is any wallet software which encrypts the wallet.dat file with our fingerprint data, so that instead of typing a password which can be compromised by a keylogger, that wallet software should use our fingerprint data and some how use that data to encrypt the wallet.dat file and it should ask for the fingerprint to send btcs etc. Do let me know if any wallet like this exists or not. If it doesn't i will try to make one.

I'm not aware of any wallet on the platforms you mentioned, probably simply due to the fact that there will be a small userbase, because phones that have fingerprint sensors in them are expensive and not everyone have them, a PC can't read fingerprints unless you buy something else too. There is however Case wallet (a hardware wallet) which does that: https://choosecase.com/ but It's sold out, so you may want to contact them to ask them If they will create more wallets.

yeah i have looked around and found about case wallets, but they are sold out as you said. But i am looking for my laptop(that's what i meant by PC). It has a fingerprint reader on it, I agree the userbase is small but it can be a game changer, same thing can be applied for face lock. I will look in to it and try to make one in my free time.

Why isn't this a really bad idea?

I remember some pretty rational discussions when fingerprint ID appeared on Samsung and Apple IOS concerning the dangers of They getting Our fingerprint data.

But here it's worse. It's not the phone or machine operating system, but an app that's getting, and intending to use, the fingerprint data.

There are other problems. I have seen a number of fingerprint scanners that didn't work reliably over time. One usually winds up working if you clean the scan surface. The other works maybe 1/10 of the time and basically is junk.

Bad idea to begin with. Your finger print is not protected from the US government, while a password is. Same with any biometric devices, such as eyes.

Well you can use finger print as an additional security layer, just like 2FA ;) I didn't say it has to be just finger print or face lock.

I am planning to make it open source, so you don't have to worry about app getting the fingerprint data, on new devices the fingerprint readers are quick and work almost 99% of the time, As for laptop's one may buy a quality fingerprint reader.

I agree with this, your fingerprint is stored in several government databases and that information will surely go out anytime soon and even if it is not shared publicly still the government will have that data.

As spunkybd said, it is better to have YOUR own password, something off the government grid.

good luck

You could build your own wallet secured on this or a raspberry pi then use the fingerprint kit to gain access to the wallet.

This document has a lot of good information regarding

Ya totally agree and crazy love that idea, a universal wallet with atomic signature and fingerprint 2FA. Sure exchanges and other wallets profit from all the different one, but thats why i am looking forward to Pillar Wallet. Will see if they can bring a change in that topic.
