I love that Minibits offers downloadable updates within the app, but I wish that they would add some sort of PIN or passcode lock option. That way, it would allow you to keep your sats secure even if somebody grabs your phone when it's unlocked.

Check Security settings. With storage encryption on, biometric auth is needed for Minibits to start.
However I do not recommend it for frequent usage, and generally better practice is to keep balances small enough in ecash to not mind such corner case.
Thanks for the explanation, I had seen that feature but also saw it's not recommended. I understand the logic of keeping the amount small. I do plan to do a run, maybe once a month, where I convert my unused sats so I can store them on Cake Wallet.
