Abut six mnths ag, smene hacked my email accunt. That means they fund ut my passwrd, then tried t use my accunt t take mney frm me and sent viruses t all my cntacts! Luckily, my friend tld me when she gt a strange email frm me, s I changed my passwrd immediately. I read abut hw t make a gd passwrd. A gd ne shuld have a mixture f bth upper case (large capital) letters(大写字母) and lwer case (small) letters, numbers and ther characters. It als shuld nt be a name r date r anything smene can guess. It shuld be cmpletely randm(随意的), that is, it shuldn’t make sense!Althugh it can be hard t remember lts f cmplicated(复杂的) passwrds, it is wrth it! These days yu can als use a passwrd manager(密码管理器). This is a special prgram that helps yu manage passwrds fr all yur different accunts.
Althugh I hpe nthing similar has happened t my readers, please cmment if yu have had a similar experience r if yu have any mre gd ideas abut making yur passwrds super safe! Catch yu later!
