If the ‘Use system lock if biometrics fail’ setting is disabled in Proton Pass on an Android smartphone, you’ll want to prevent anyone from logging in using the password.
However, if a fingerprint is added in the smartphone settings, this setting can be bypassed.
This constitutes an unintended bug and, potentially, a security risk if the lock screen password is shared, as users may believe they cannot log in to Proton Pass using the password.
