3 reasons to never use fingerprint locks on phones

Fingerprint locks—Touch ID on iPhones —may be easy to use, but they are far from perfect. After reviewing the risks, you may want to return to using PINs and passwords.

We officially have a password problem. The average user in 2015 had at least 90 online accounts, says Dashlane, maker of a popular password manager. In the UK, the number was 118. In the US, a whopping 130. Even more troubling, we store far too many login details on our phones and tablets (I am certainly guilty of this), meaning anyone with access to our phones can also access our accounts.
