    The average computer user has between 5 and 15 username/password combinations to log in different kinds of accounts. Some demand you use a specific number of symbols and digits, while others require you to change your password every 60 days. The feeling of confusion resulting from memorizing these login information has grown so common that it actually has a name: password fatigue(疲劳).

Having to remember so many different passwords is annoying, but it can also be dangerous. Because it is virtually impossible to remember a unique password for each of these accounts, many people leave handwritten lists of usernames and passwords on or next to their computers.

1. While these practices make it easier to remember login information, they also make it easier for thieves to hack into accounts.

Single Sign-On (SSO) confirmation and password management software can help solve this problem. With SSO, users only need to remember one password to log in to the main system.

2. SSO software is typically used by large companies, schools, or libraries.

3. If a user loses or forgets the password required to log in to SSO software, the user will then lose access to all of the applications linked to the SSO account. Users who rely on password management software face the same problems.

Although most websites or network systems allow users to recover or change lost passwords by providing email addresses or answering a prompt(提示), this process can waste time and cause further frustration. What is more, recovering a forgotten password is only a temporary solution. 4.

Some computer scientists have suggested computers rely on biometrics(生物测定学). 5. The use of biometrics raises questions concerning privacy and can also be expensive to practice.

Software engineers and computer security experts are still searching for the cure to password fatigue. Until they find the perfect solution, however, everyone will simply have to rely on the password system currently in place.

A.It does not address the larger problem of password fatigue.

B.These software programs have been built into many major web browsers.

C.The problem with password management software makes users feel powerless.

D.The SSO software then automatically logs the user in to other accounts within the system.

E.However, SSO confirmation and password management software also have drawbacks.

F.This is a method of recognizing human users based on unique traits, such as fingerprints, voice, or DNA.

G.Others solve this problem by using the same password for every account or using extremely simple passwords.
