Passcode device policy 编辑

Create a passcode policy in Endpoint Management based on your organization’s standards. You can require passcodes on users’ devices and can set various formatting and passcode rules. Create policies for iOS, macOS, Android, Android Enterprise, and Windows desktop/tablet. Each platform requires a different set of values, which are described in this article.

To add or configure this policy, go to Configure > Device Policies. For more information, see Device policies.

iOS settings

• Passcode required: Select this option to require a passcode and to display the configuration options for an iOS passcode device policy. The page expands to let you configure settings for passcode requirements, passcode security, and policy settings.
• Passcode requirements
  • Minimum length: In the list, click the minimum passcode length. The default is 6.
  • Allow simple passcodes: Select whether to allow simple passcodes. Simple passcodes are a repeated or sequential set of characters. The default is On.
  • Required characters: Select whether to require passcodes to have at least one letter. The default is Off.
  • Minimum number of symbols: In the list, click the number of symbols the passcode must contain. The default is 0.
• Passcode security
  • Device lock grace period: In the list, click the length of time before users must enter a passcode to unlock a locked device. The default is Immediately.
  • Lock device after inactivity: In the box, enter the length of time a device can be inactive before it is locked. The value can be between 1 and 15 minutes. Set the value to None to disable the policy. The default is None.
  • Passcode expiration in days (1-730): Type the number of days after which the passcode expires. Valid values are 1–730. The default is 0, which means the passcode never expires.
  • Previous passwords saved (0-50): Type the number of used passwords to save. Users are unable to use any password found in this list. Valid values are 0–50. The default is 0, which means users can reuse passwords.
  • Maximum failed sign-on attempts: In the list, click the number of times a user can fail to sign in.
    • If you set this number higher than 6, after the sixth attempt, the device imposes a time delay between attempts. The time delay increases with each failed attempt. After the final attempt, all data and settings are securely erased.
    • If you set the number at 6 or lower, the device is erased without implementing a time delay.
    • If you select Not defined, after 6 attempts, the devices imposes an increasing time limit between attempts but is not wiped.

    The default is Not defined.

• Policy settings
  • Remove policy: Choose a method for scheduling policy removal. Available options are Select date and Duration until removal (in hours)
    • Select date: Click the calendar to select the specific date for removal.

    To encrypt their devices, users must start with a charged battery and keep the device plugged in until encryption completes. The process can take an hour or more. If they interrupt the encryption process, they can lose some or all data on their devices. After a device is encrypted, the process can’t be reversed except by doing a factory reset, which erases all the data on the device.
