2) A.9.2.4 Management of secret authentication information of users: I give you your password in a secure manner (according with a procedure), for example: the organization needs to verify your identity, the use of external parties or unprotected electronic messages should be avoided, you should acknowledge receipt of secret authentication information, etc.
3) A.9.3.1 Use of secret authentication information: You should follow the organization’s practices in the use of passwords, for example: not share individual user’s secret authentication information, ensure proper protection of passwords, not use the same secret authentication information for business and non-business purposes, etc
