You can establish a password policy to prevent users from setting weak passwords.
This page describes the steps to configure settings for the password policy and how to calculate the password expiration period.

The following items are applied to users when they set their passwords in their "Account Settings".

• Minimum Number of Characters for the User Password
• Minimum Number of Characters for the Administrator Password
• Password Complexity
• Allow users to use login name as password
• Password Reuse Limit

If you clear "Allow users to reset password", only cybozu.cn Administrators can change users' password.
Even when cybozu.cn Administrators change users' password, the password policy is not applied.
Consequences for password policy

   • Minimum Number of Characters for the User Password
     This setting is applied to all users except cybozu.cn Administrators.
   • Minimum Number of Characters for the Administrator Password
     This setting is applied to cybozu.cn Administrators.

5. Select password complexity requirements.

6. Specify whether to allow users to use their login names as their passwords.
   For security reasons, we recommend you not to enable this option.

   Previous passwords include passwords that have been changed by both users and administrators.

   Password Expiration Period
   

9. Click Save.

When the number of days remaining before the password expires is five or less, a message appears on the page after login that displays the number of days remaining and prompts you to change the password.
However, if you are using the mobile app, you will not be notified of the number of days remaining before password expiration.

The password expiration is calculated starting from the date and time when the user changed the password.

For example, assume that User A changed the password on March 1st at 10 AM.
Then, on March 25th, one of cybozu.cn Administrators changed the setting of password expiration period to 30 days.
In this case, the password for User A will be valid from "March 1st, 10 AM" to "March 30th, 10 AM" which is 30 days after the start date.
