This is primarily focused on the desktop version of the application. On my iOS device, I can already require Face ID, but I’d love to see enhancements to the App Lock feature in Proton Mail and Authenticator. Specifically, adding the option to use biometric authentication (fingerprint or face recognition) or a passcode would provide an extra layer of security and convenience. This would give users greater flexibility in protecting access to their 2FA codes while also aligning with best practices for securing sensitive applications.
