Allowing an app to access our photographs on our mobile devices is a dangerous permission. For all we know, we might be unwittingly giving away facial recognition data which is actually stronger than a password that is vital and essential to mobile banking in order for us to do online transactions. We might become victims of identity theft and suffer financial loss because some apps may apparently mine and harvest our data particularly biometrics for purposes we are not aware of. In a similar way, we should not rely on the fact that, just because others do it, it is already safe. Hence, it is best to consult information privacy professionals or IT experts on the matter.
