Bitcoin Forum

I think one of the many interesting bitcoin (or alt) applications that could be done with blockchain technology could be is Passcoin or Pwdcoin or Passwordcoin.

At the moment we have very unreliable methods to store the many thousands of passwords that people keep to use internet. Some use LastPass, or some other use Keepass

Both are unreliable. Lastpass is centralized in a country where the state can request to have a backdoor and not let anybody know.
Keepass cannot be stored on the internet easily. In case your house burns, or you get kicked out of your house by your wife, you are bombarded or you have to cross a frontier (almost nude and without belongings) you will lose all your digital life.

I think a math proof encryption method to just store a few hundreds of passwords or even just a master key that generates many hundreds of different possible passwords aka deterministic wallets (but applied to password conventions instead of bitcoin addresses) could have a huge impact as millions would use such technology.

If somekind of deterministic method to generate passwords from a master key could be included into bitcoin it would be wonderful.

A non centralized controllable store of passwords or secrets that is persistent and cannot be shut down  and no nsa risks.


Just a thought. Any opinions?

I make use of Keepass and as you say, you are out and out reliant on the tech on which it runs. You need to ensure that you have updated backups in several places should something bad happen i.e. HDD failure or similar. If the backup file is damaged in any way you are screwed.

If it was like a HD wallet all you would need is the seed in order to rebuild anything. Being able to save your passwords in this way would be great and definitely something I would look at should it ever become available.

Would be nice if it could be made to work like a Trezor kind of setup.

not a bad idea..but how about you keep your pwds on cloud svr. especially that storj project is near ready..cloud decentralized storage. using blockchain tech..

I think that could be an interesting chance,storj claims that they would not be able to access anyone files are they don't have any file in their servers.
besides,storj files would be multi redundant and encrypted,which add the files a good security system

Well for me it's not that i don't have confidence in encryption technology and how advanced we have progressed, it's just that i would still favor good old method of trying to remember things. One part of the password in a safe box, fire proof of course and not letting anyone know which account is for. The other easy to remember part in my head... talk about old school  ;D

Using blockchain to store passward is not secure enough to avoid hacking. such as Trojan horse, virus etc is alway there. Due to that, many ppl are losing bitcoin.

I don't trust blockchain enough to keep my password using that security. it's faulty and might lose my bitcoin. cloud is a good idea I guess.

Yeah, I know a guy who lost his btc because of this.

??? Huh? It's very easy.
