account​_policy​_data

Additional macOS user account data from the AccountPolicy section of OpenDirectory, the identity provider used by Apple.

Column Type Description
creation_time double When the account was first created
failed_login_count bigint The number of failed login attempts using an incorrect password. Count resets after a correct password is entered.
failed_login_timestamp double The time of the last failed login attempt. Resets after a correct password is entered
password_last_set_time double The time the password was last changed
uid bigint User ID

Example

Query the creation date of user accounts. You could also query the date of the last failed login attempt or password change.

SELECT strftime('%Y-%m-%d %H:%M:%S',creation_time,'unixepoch') AS creationdate FROM account_policy_data;

See each user's last password set date and number of failed logins since last successful login to detect any intrusion attempts.

SELECT u.username u.uid, strftime('%Y-%m-%dT%H:%M:%S', a.password_last_set_time, 'unixepoch') AS password_last_set_time, a.failed_login_count, strftime('%Y-%m-%dT%H:%M:%S', a.failed_login_timestamp, 'unixepoch') AS failed_login_timestamp FROM account_policy_data AS a CROSS JOIN users AS u USING (uid) ORDER BY password_last_set_time ASC;

Notes

  • The values in this OpenDirectory table are related to account creation. In the past, it was fairly common to use OpenDirectory to have a home folder (~) on a server, and then log in and get that folder wherever they are. (These days, this use case is more uncommon.)
  • To determine who is logged in to the Mac, or for example, to check the record name versus the computer's "short name", consider using the data in the DSCL table.
