hello @lupafilotaxia,
web security must be a culture, although many platforms are very secure, we must remember the way most websites were designed, these platforms were created to be as easy to use as possible, this means that passwords must be easy to recover and transactions must be simple, that is why with wallets like metamask that do not have two factor authentication we must be very careful when associating them with any web service as fraudsters will do everything they can to get you to give them access, then they simply steal whatever is in that wallet.
