This is the number of days for which a MarkVision Professional user account password is valid. Never means the password will never expire and a number means that the password will expire after the listed number of days. Counting starts from the last date that the account password was changed.
| Note: | This expiration period applies to all users except the Administrator. Once the interval is set, it is recommended that you do not modify the expiration period again, so that users do not become confused. |
