Choosing a unique password for anything can seem a bit frustrating and you might use an easy to remember one if you don't want to waste time.

However, some passwords are easier to hack than others, and there are five in particular that would be best to change if you use them currently.

As reported by The Daily Express a new study from card machine provider Dojo, analysed data from some 100,000 breached passwords shared by the National Cyber Security Centre (NCSC).

Through this, it found passwords based on pet names or terms of endearment were the most likely to be hacked.

Additionally, easy to remember phrases like '123456' and 'Password' are among the most vulnerable logins.

What are the 5 passwords you need to change if you use them?

The top five commonly hacked passwords with the most users were revealed to be:

1. 123456 (23.2million users)
2. 123456789 (7.7million users)
3. Qwerty (3.8million users)
4. Password (3.6million users)
5. 1111111 (3.1million users)

Speaking about the findings, Naveed Islam, chief information security officer at Dojo, said: "Passwords are the digital keys for just about everything on the Web, from checking emails to online banking.

"The surge in online services has resulted in a proliferation of password usage. This has resulted in password fatigue - the feeling experienced by many people who are required to remember an excessive number of passwords as part of their daily routine.

"To cope with password fatigue, people reuse the same password across multiple websites, using simple and predictable password creation strategies. Attackers exploit these well-known coping strategies, leaving individuals vulnerable.

"Using a password manager to create unique passwords and using multi-factor authentication (MFA) across all websites are some of the recommended ways to improve password security and make it difficult for attackers to steal your passwords and access your data. Frequently check a breach notification site to see if any of your passwords have been leaked in any data breaches. If it has, change your password for that account immediately."
