According to Google and Apple security protocols, Passkeys are encrypted using your device's Screen Lock.
If you disable your Passcode/Pattern in the device settings, all Passkeys on that device will be invalidated or deleted to protect your safety.
Consequence: You will lose access to Bullbit.
Solution: You will be forced to use your Secret Code to recover the wallet from scratch. Therefore, never disable your screen lock while using a Passkey wallet.
