Many cases in which someone’s password has been compromised have occurred when an attacker has cracked someone’s password on a low-security site, but the victim has used the same password for another, high-value site. Therefore you should take care not to use the same password for all your online activities.
Using passwords to protect your data
Your laptops, computers, tablets and smartphones will contain a lot of your personal data, business-critical data, personal information of your customers and also details of the online accounts that you access. It is essential that this data is available to you, but not available to unauthorised users.
When used correctly passwords are an easy and effective way to prevent unauthorised users accessing your devices.
- Tip 1: Make sure you switch on password protection
Set a screenlock password, PIN, or other authentication method (such as fingerprint or face unlock).
- Tip 2: Use two-factor authentication for 'important' accounts
If you’re given the option to use two-factor authentication (also known as 2FA) for any of your devices or accounts, you should do. 2FA significantly increases your security for not much extra effort. 2FA requires two different methods to 'prove' your identity before you can use a service, generally a password plus one other method. This could be a code that's sent to your smartphone (or a code that's generated from a bank's card reader) that you must enter in addition to your password.
The current Government guidance on creating a strong password is to use 3 RANDOM WORDS for example: microwaveshelldash.
Howsecureismypassword.net estimates this password would take 23 million years to crack.
