以编程方式打开设备密码更改 android

Question

How can I programmatically open the Change Password Screen under Settings -> Security -> Choose screen lock -> Password.

Right now I am using the following code and its getting me as far as Settings -> Security -> Choose screen lock, but I want to force the Password option. Not swipe or pin option.

R.id.change_phone_password:
Intent change = new Intent(DevicePolicyManager.ACTION_SET_NEW_PASSWORD);
startActivity(change);

I am running Android 10.

You need to use the "setPasswordQuality" API of the android DevicePolicyManager. You app has to be registered as a device admin app in order for it to use this API. This API will let you specify password quality as something, numeric, alphanumeric etc. You can also look at other APIs like "setPasswordMinimumLength", "setPasswordHistoryLength", "setPasswordMinimumUpperCase" for more control over what type/length of password you want your endusers to use. All this is only possible if you app is a device admin app.
