RealWear Foresight administrators can require HMT device users within their Foresight instance to set up a device PIN to unlock their HMT device. PIN configuration requirements have changed undergone changes from Android 8 to Android 10. If you have updated (or plan to update) your HMT software to Release 12 and are a Foresight administrator, review this article to learn more about Foresight PIN requirements and configuration.
This article contains requirements on PIN settings and references to Android 10 where you can learn more about the change.
Note: PIN length is no longer supported in RealWear Firmware Release 12 (based on Android 10). Customers have the option to configure PIN complexity when enabling a PIN on devices running this firmware.
The device PIN length setting relies on a legacy device admin policy named USES_POLICY_LIMIT_PASSWORD. This policy has been deprecated in Android 10, which is the base for RealWear Firmware Release 12.
Android 10 prevents apps and DPCs from applying legacy device admin policies. We recommend customers and partners transition to fully managed devices or work profiles. The following policies throw a SecurityException when invoked by a device admin targeting Android 10:
|11.x and below||User customizable PIN length|
|12.x and above||User selectable PIN complexity|
Starting with firmware 12, you will not be able to specify the number of digits in the PIN. You can specify only the required complexity level.
|PIN Complexity Setting||Acceptable Values|
|LOW2||PIN with repeating (4444) or ordered (1234, 4321, 2468) sequences|
|MEDIUM3||PIN with no repeating (4444) or ordered (1234, 4321, 2468) sequences, length at least 4|
|HIGH4||PIN with no repeating (4444) or ordered (1234, 4321, 2468) sequences, length at least 8|
User defined PIN length of 4 – 16 digits.
We recommend updating your devices to the latest firmware and use PIN complexity.
There is no clear 1-1 mapping between PIN length and PIN complexity. For example, a PIN length of 6 digits in firmware 11.x (based on Android 8) does not have an equivalent PIN complexity setting in firmware 12.x (based on Android 10).
|PIN Length||PIN Complexity||Notes / Requirements|
|LOW complexity allows repeating (4444) and ordered (1234, 4321, 2468) digits|
MEDIUM complexity does not allow repeating (4444) or ordered (1234, 4321, 2468) digits
|8||HIGH||HIGH complexity does not allow repeating (44444444) or ordered (12345678, 87654321) digits|
