Password re-use is problematic as a security breach on one site could compromise a users security on every other site the password is in use.
Of course, that comes far down the list after more logical ones like "123456" and "password", but nevertheless: If your password is "blink182" ... please change it!
Facepalm: In today's digital age where most consumers know their modems from their motherboards, one might imagine that the quality of people's passwords has improved. Some 23.2 million people used "123456" as their password, only to find their code was cracked. Around 3.8 million users have using "qwerty" as password which is the first six letters on the top row of a standard keyboard.
If you think it's time for a security upgrade, then read on.
If you're using it to access any of your accounts, you should probably change that, maybe to something a little more complicated, like "ALLTHEsmallTHINGS", or "Whatsmyageagain23".
They accessed breached information with the help of Troy Hunt's "Have I been pwned" database and found that more than 23 million people had 123456 as the password for their online accounts.
Sunshine continues for Easter Monday UK News
The weekend is forecast to remain warm and sunny, although there may be some cloud on Easter Monday and it will be cooler. Scotland's record was broken on Sunday afternoon, with the mercury hitting 22.8C at Fyvie Castle in Aberdeenshire.
The study also surveyed 1,350 United Kingdom citizens, and found that only 15 per cent of respondents felt they knew a great deal about protecting themselves from harmful activity online, with 46 per cent of respondents agreeing that information about how to be secure online is 'confusing'.
"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 favourite band", NCSC technical director Ian Levy said in a press release.
These were followed by 1111111, 12345678, abc123, 1234567, password1, 12345, 1234567890, 123123, 000000, and Iloveyou.
We typically haven't done a very good job of that either as individuals or as the organisations asking us to register with them. Hoppus responded to the report with a simple, "You guys". First, the important thing is that your Password needs to be strong, and they should also be unique across each of your different accounts. "Be creative and use words memorable to you, so people can't guess your password", explained Levy. The master password is the only password you need to remember.
Developers and sysadmins are advised to make use of the list to encourage users to create stronger passwords, with the suggestion being that passwords from the list should be blocked. You can also use a long password which can be the key factors in keeping you safe.
