Using encryption and blockchain technology, b.lock is a Chrome extension that helps you manage your passwords in a secure and trustless way such that only you have access to them.
- You can save the login credentials for different websites to b.lock. The saved credentials will be auto-filled when you visit the websites subsequently.
- You can also save "Secret notes" such as bank PIN numbers, metamask seed words,...
- b.lock acts as a Nebulas wallet as well. You can use it to keep NAS or send NAS to other accounts.
- b.lock uses the Nebulas blockchain and each user account is linked to a Nebulas account.
- b.lock uses your Nebulas private key (in other words, the master key) to encrypt your passwords and secret notes, using the AES-256 encryption algorithm.
- b.lock saves the encrypted passwords/secret notes on the Nebulas blockchain.
- Hence, your passwords will be accessible to you anytime and anywhere, as long as you have your private key
- No one but you can decrypt the encrypted passwords. Thus, you are truly in control of your passwords.
- Step 1: Download the chrome extension from here
- Step 2: Following the extension’s intructions, create your “keystore” (which is like your master key) and back it up. You can also import your existing Nebulas keystore.
- Step 3: Go to this link and get your free Nebulas coins (which is needed to run b.lock. Don’t worry, $0.0001 worth of the coin is enough to use b.lock for your lifetime. Hence, we are giving it free to you)
- Step 4: Done, you can start using b.lock to save your passwords/secret notes
- Password managers are essential these days, when we have to manage lots of different passwords (which shouldn't be reused)
- There are lots of potential problems with the existing centrailized password managers:
- Single point of failure: if the server/database goes down, there goes your passwords
- Trust issue: can you really trust that these closed-source softwares will not just read your passwords?
- b.lock solves all of these problems:
- The passwords are stored on the decentralized database that is the Nebulas blockchain, hence it will not go down easily
- The passwords are encrypted by your private key which belongs to only you. You are the only one who can see your saved passwords.
