SB016 Does not re-use passwords between accounts

Using unique passwords ensures that if one of your passwords is leaked, not all your accounts can be accessed.


Why is it important?

Good password hygiene is key for protecting accounts. If important accounts are protected with the same password, a leaked password may be able to access them all. Using a unique password reduces this risk.
