It’s IMPOSSIBLE to reset the PIN code, you have to remember it once you set it. If you don’t remember it anymore, please try it by yourself, you have 5 times to try it every 24 hours.
Here are some suggestions:
1. You’d better note every possibility, don't waste the chance.
2. Don't try simple combinations, such as 111222, 111111, etc. The app doesn't recommend you to set up a PIN like this.
To help users remember the PIN code well, our Messenger asks users to input the PIN code every 24 hours when they open the wallet.
