Please create and use long passwords with a minimum length of 10 characters or more.
A simple rule is to use long phrases and then take 1-2 beginning letters of each word and join them to create a password. This way you just need to remember the phrase but not the password itself which is much easier.
Here is an example phrase and shortened password in result of the phrase.
Phrase : “I was born in Johor Bahru on 1st January 1980”
Password : “IwbiJBo1180”
Here is a link to a study explaining why it’s necessary to create longer passwords.
