Some of this is to make passwords harder to guess / harder to brute-force. Some of this is to satisfy regulatory requirements - so credit card transactions have particular restrictions / two factor authentication or similar. One of the bits of advice is to use long passwords made up of three random words and to use a different password per website / to use your web browser to generate an appropriate random password. Forcing passwords to change regularly may not be a good way to maintain security - it can mean that people use password01, password02 and things like that. With every good wish as ever Andy Cater
