What can we do with passwords?

Password, it's hard to say you love you

Generally, we recommend that you use a unique, complex, and preferably containing a weird character password, but you will not be able to remember these passwords as "willful, we recommend that you set different passwords when logging on to different websites!

Computer users need a password manager to help remember complex logon creden。, but most people think this is not necessary at all.

What then? People continue to use passwords similar to "123456", their birthdays, or Idol names as "secure" passwords.

Ideally, you can use password management software to generate complex and random passwords and retrieve them whenever you need them. However, ordinary people do not think this is a perfect solution. In particular, it is a pity that the online password hosting platform LastPass has been intruded recently.
Therefore, we must find other better solutions.

KUANG! Emoticons and passwords

A British technology company demonstrated a solution to password problems last week-emoticon password.

This is indeed a good idea, especially when surveys show that it is easier for people to remember the plots and pictures, rather than numbers or words.

The company cooperates with banks to develop the interfaces and systems required for using our online accounts. Although the prototype they present is not the final product-the Bank app, it can at least be inferred that this is customized to meet the needs of banks, at the same time, we can clearly understand how the system works.
What is the facial expression password?

First, it seems that no bank is likely to force users to use emoticon passwords. Even a person with a bad temper like me will be deeply disgusted with the sales promotion of the box, let alone middle-aged and elderly people with vision, it is even difficult for them to differentiate each "small yellow face.


So if you like to use a password or a PIN password, it doesn't matter, you can continue to use it (the bank is also willing to do so ). However, if you decide to set an emoticon password, you can see this interface:


Although the password demonstrated here only needs to select four emojis, it is entirely dependent on the bank. Setting it to six, eight, or more is a breeze. The more characters, the more secure it is.

You may also notice that this is not a "normal" expression in the standard operating system, but rather a self-developed expression by the company. This is also intentional, because many small yellow faces only have slight differences, which makes it more difficult to set and remember passwords.

Obviously, different banks can design and select their own expressions as they wish. For example, some people do not like casual expressions.


In addition, this design does not provide a large number of expressions, thus avoiding the user from making some "difficult" choices. In the demo, they provided 44 emojis (the figure in the upper-right corner of the keyboard is a delete key ).

44 expressions may not sound too many, but the traditional four-digit password only provides 7290 non-repeating numbers. There are also four passwords. Using 44 emoticon passwords can generate nearly 3.5 million combinations of passwords.

This is undoubtedly an improvement, but other aspects need to be considered.

For example, should a random expression be used to prevent specific expressions from being selected based on personal preferences? For example, if the screen is static, do we habitually choose the upper left corner as the password? A dancer with scissors is playing football in the sun. Will the facial expression and password with stories become the next hot topic ?!


In addition, the author suggests that in the future, the emoticon passwords of any system will be sorted randomly. Of course, different banks can choose different emoticon, which helps prevent users from using the same password in different systems.

Curiously, how will users record their emoticon passwords and will they draw them on paper with a pen? But in general, emoticon passwords are still a novelty, but they are gradually becoming more people's habits and needs.

Bank password security

We attach great importance to the security of banks. After all, the more banks occupy, the more losses they may cause.

This makes us deeply worried about the simple 6-digit password used by bank accounts, not the complex password requirements of other websites.

Although the ATM is simple, you still need to provide bank card information for operation. The Bank seems to be sending a strange signal to users: A password from 000000 to 999999 is enough to protect all your wealth.

In the future, we may be lucky to see a digital keyboard replaced by a facial touch screen on the ATM, although this may take some time. But don't be surprised when your bank APP starts to ask your facial expression password soon!
