EthPass
It's similar to a password manager like LastPass, but it uses Ethereum as a back-end for decentralization purposes, rather than something like AWS. It also uses MetaMask to encrypt and decrypt your data.
FAQ
Q: Can you, or anyone else see my data? A: Everyone can see the encrypted data, but only you (theoretically), can see the decrypted data.
Q: Can people see the encrypted versions of my passwords? A: Yes, since Ethereum is essentially a large public computer. However, only your private key can decrypt them.
Q: Do you need Ethereum to use it? A: You need to be able to interact with the Ethereum network to use it, so we recommend the browser plugin MetaMask, the Mist browser, or, you can manually create your own transactions.
Q: Does it cost money? A: It costs a small network fee to store data on the blockchain, however, it is free to read and decrypt them.
Q: Is it open source? A: Yes, you can see how it works.
Q: Can I store my passwords offline, and not sync them to the network? A: Yes. This way, you also won't have to pay a miner fee, but you lose the benefits of decentralization.
