According to CalcPark.com [1]https://calcpark.com/password-strength-checker/, you can beat the hackers by choosing a password long enough (at least 12 characters). A strong password is also difficult to guess because it consists of random characters only rather than meaningful words. A strong password basically looks like this: S + GfV $% # Rae8.
The time it takes for a hacker to crack your passwords depends on mainly the following factors:
- Number of characters (the longer, the better)
- The type of characters used in the password (the more variety, the better)
Guidelines for choosing good passwords to make passwords harder to discover:
- Use a minimum password length of 20 or more.
- Include lowercase and uppercase alphabetic characters, numbers and symbols.
- Generate passwords randomly.
- Avoid using the same password twice.
- Avoid character repetition, keyboard patterns, dictionary words, letter or number sequences.
- Avoid using information that is or might become publicly associated with you.
- Avoid using information that your colleagues and/or acquaintances might know to be associated with you.
- Do not use passwords which consist wholly of any simple combination of the aforementioned weak components.
- Use of a password manager is recommended by the National Cyber Security Center[2]https://www.ncsc.gov.uk/blog-post/what-does-ncsc-think-password-managers.
