Line 30: '''Disadvantages of mobile phone two-factor authentication:''' * Not everyone has a mobile phone, and the cost of a new phone and/or carrier plan is often significant. * [[Text message]]s may cost the user money to receive, discouraging use; mobile roaming fees tend to be higher when the user is away from home or in another country, a time when secondary authentication is more likely to be requested. * The mobile phone must be carried by the user, charged, and kept in range of a cellular network whenever authentication might be necessary. If the phone is unable to display messages, access is often impossible without backup plans. * The user must share their personal mobile number with the provider, reducing personal privacy and potentially allowing [[Mobile phone spam\|spam]].
