Remarks
Called by an application that is administering the device to set the password restrictions it is imposing. After setting this, the user will not be able to enter a new password that is not at least as restrictive as what has been set. Note that the current password will remain until the user has set a new one, so the change does not take place immediately. To prompt the user for a new password, use #ACTION_SET_NEW_PASSWORD or #ACTION_SET_NEW_PARENT_PROFILE_PASSWORD after calling this method.
Quality constants are ordered so that higher values are more restrictive; thus the highest requested quality constant (between the policy set here, the user's preference, and any other considerations) is the one that is in effect.
On devices not supporting PackageManager#FEATURE_SECURE_LOCK_SCREEN feature, the password is always treated as empty.
The calling device admin must have requested DeviceAdminInfo#USES_POLICY_LIMIT_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.
Apps targeting android.os.Build.VERSION_CODES#R and below can call this method on the DevicePolicyManager instance returned by #getParentProfileInstance(ComponentName) in order to set restrictions on the parent profile. Apps targeting android.os.Build.VERSION_CODES#S and above, with the exception of a profile owner on an organization-owned device (as can be identified by #isOrganizationOwnedDeviceWithManagedProfile), will get a IllegalArgumentException when calling this method on the parent DevicePolicyManager instance.
<strong>Note:</strong> Specifying password requirements using this method clears the password complexity requirements set using #setRequiredPasswordComplexity(int). If this method is called on the DevicePolicyManager instance returned by #getParentProfileInstance(ComponentName), then password complexity requirements set on the primary DevicePolicyManager must be cleared first by calling #setRequiredPasswordComplexity with #PASSWORD_COMPLEXITY_NONE) first.
<p><string>Note:</strong> this method is ignored on {PackageManager#FEATURE_AUTOMOTIVE automotive builds.
This member is deprecated. Prefer using #setRequiredPasswordComplexity(int), to require a password that satisfies a complexity level defined by the platform, rather than specifying custom password requirement. Setting custom, overly-complicated password requirements leads to passwords that are hard for users to remember and may not provide any security benefits given as Android uses hardware-backed throttling to thwart online and offline brute-forcing of the device's screen lock. Company-owned devices (fully-managed and organization-owned managed profile devices) are able to continue using this method, though it is recommended that #setRequiredPasswordComplexity(int) should be used instead.
