A password manager can store lots of sensitive information like passwords, pins and so on. To access this data, we should use a strong password/passphrase in order to protect our data. This password is more or less a master password.
Is there any reason why I should change this password regularly?
In my case, I use KeePass with a strong password that is only known by me. Furthermore, I would like to exclude password manager solutions like LastPass (who got hacked lately) since online accounts should have changing passwords.
