App Access Security (PIN/Password Lock)

I’m a big fan of sudowrite and use it quite often. I'm writing to ask if there are plans to add an extra layer of security, such as a PIN or a password lock, before accessing the app or specific folders?

Currently, I log in via Gmail. Although I have 2FA enabled and feel safe for now, I’ve recently had security concerns with another email account that was targeted by hackers. To be clear, everything is safe and under control now, but the experience left me feeling quite anxious about my digital security. To give me extra peace of mind, I would love to see a feature that allows a secondary password or PIN for app entry. I think it would be a great way to provide an added sense of protection for all users.

Please kindly consider this suggestion. Thank you for all your hard work on this amazing app!
