On Android 14 DP2, a toggle allows you to enable auto-confirm correct PIN on your Pixel
XDA was going through the recently released Android 14 Developer Preview 2 and when setting up a new PIN, a new “auto-confirm correct PIN” toggle was spotted; while it didn’t appear to be operational, the description under the toggle confirmed what the feature does. It says, “Unlock automatically if you input a correct PIN of 6 digits or more. This is slightly less secure than tapping Enter to confirm.” The toggle will not appear if your PIN is less than six numbers in length.
Besides noting on the screen that the “PIN must be at least 4 digits,” Google added, “but a 6-digit PIN is recommended for added security.” The feature can be enabled or disabled after you’ve set up the PIN on your phone by going to Settings > Security & privacy > Device lock > Screen lock. Tap on the gear icon and you’ll see the “auto-confirm unlock” toggle that can turn the feature on or off.
