Is the code "sealed" in Cary?

We have talked a lot about the problem of the password, and have thought about the existing account and password design. It's a good thing to explore the code because it looks like a chicken, but it's especially important.

Passwords have a risk of being hacked in software, and hardware such as fingerprint recognition has recently been exposed to security issues. Today we are going to introduce a solution from a start-up company: "Seal" the Code in Cary.

This card, called the QWERTY cards, looks like a purple, similar in size to a regular credit card.

Working principle?

This card generates a password in 3 steps:

1. The string "sh" on the grid key above the card is the first component of the/J3HQ;

2, the second part will be chosen by the user a word as secret word, such as you can choose Enigma this word, control the key on the card, will enigma translated into the code is "Afqsu." ；

3, the third part is the name of the specific site, such as Amazon site is Amazon, also according to the key rules translated into code, that is, ". U.rqf".

As such, your account password on Amazon is made up of these three parts: your password = "sh (/j3hq" + "AFQSU.") + ". U.rqf" = "sh" (/j3hqafqsu. U.RQF ".

Every cipher card sold by the QWERTY cards is randomly generated, which means that the user gets a unique combination of characters from the card in hand to ensure the security of the password. By putting this QWERTY card in your wallet, users save the hassle of memorizing passwords, and the robustness of each site's passwords is considerable. However, every time you enter a password to carry this card, it may be the product of a larger slot point.

The other question is, what if I lose my card?

Each card sold by the QWERTY cards is fitted with a vinyl letter containing a string of reset passwords, which, if lost, can be used to open all Web site account changes with the password, and the old card will fail at the same time. This card currently has a relatively imperfect place, for some can only use numbers or a certain length of the password site, the QWERTY cards generated by the password may not conform to the site password rules, at this time can only be adjusted by the user.

Similar to the QWERTY Cards password card and Passwordcard, recommended to their official website to see, the working principle is similar.

Currently, the QWERTY cards is priced at $4.99 per card, and is also covered by mail. Do you think that's a reliable way?
