What are 3 things you should avoid when creating passwords?

DON'T use blank spaces in your password. DON'T use a word contained in English or foreign language dictionaries, spelling lists or commonly digitized texts such as the Bible or an encyclopedia. DON'T use an alphabet sequence (lmnopqrst), a number sequence (12345678) or a keyboard sequence (qwertyuop).

Why do we need to set password for your user accounts?

Passwords provide the first line of defense against unauthorized access to your computer and personal information. The stronger your password, the more protected your computer will be from hackers and malicious software. You should maintain strong passwords for all accounts on your computer.

Should users be forced to change passwords?

For all these reasons, forcing users to change their passwords regularly or implementing rigid policies about password length and complexity just don't work. And that's why NIST and even large enterprises like Microsoft do not recommend mandating periodic password changes.
