QR Codes Might Spell the End of Passwords


When you log into your e-mail account, Facebook account and other online properties, you are bound to use a user name and password. This helps the service or the Web site know for sure that you are who you say you are.

However, while it works to authenticate you, it might not be foolproof. A cybercriminal can steal your passwords using a variety of attacks, including man in the middle, database hacking, keyloggers or even brute force. This is the reason why site owners have always been on the lookout for something better.

Some sites are now using a two-step authentication or even third party login services. Both of which has their own weak points.

Now you have an alternative. Steve Gibson who is a security enthusiast has introduced SQRL, which means Secure QR Login. The new system would be using QR codes and will help you do away with user names and passwords.

For example, if you want to log into a certain online service, you will be presented with a QR code. You can then scan that QR code with your smartphone and that is it, you can now access your account.

How does it authenticate you? The SQRL app will be storing a secret code on your smartphone. Nobody will know that key. When you scan the QR code from the site, the app will create both a public key and private key for you. It will then send these to the site to authenticate your identity even without a user name or password.

This system is very simple and actually lessens the work on the part of the user. In addition, there is no chance that a hacker could steal your credentials. Further, it does not make use of third party logins.

Do you think that this would eventually replace passwords? Tell us your thoughts in the comments!
