CS02 Password Security

 

The average person has dozens of accounts across the internet.

 

These might be email addresses, online banking, or social networks like Facebook and Instagram.

 

They might also be for websites we’ve used once and never gone back to.

To create these accounts, you need a password. This password should be unique, meaning you’ve not used it anywhere else.

Computer experts know this, and they advise people not to re-use their passwords.

 

But let’s be real: nobody can remember dozens of passwords for different sites. It just can’t be done.
