With so many different online accounts to keep track of, remembering all of your passwords can be a challenge. It might seem like the simplest option is to pick something easy and use that as your password for everything. But this poses a security risk. Different people all over the world often go for the same simple passwords, making it easy for hackers to access their accounts. UK experts carried out a survey into the passwords most vulnerable to hacking and, unsurprisingly, if yours is something like ‘123456789’ then it might be time for a change.

The NCSC said that safe passwords should include “three random but easily memorable words strung together” NCSC technical director Ian Levy told Techcrunch, "Password re-use is a major risk that can be avoided. Nobody should protect sensitive data with something that can be guessed, like their first name, local football team or favorite band. "Using hard-to-guess passwords is a strong first step and we recommend combining three random but memorable words. “Be creative and use words memorable to you, so people can't guess your password.” This article originally appeared on our sister site, Yorkshire Evening Post
