Two-factor authentication (2FA) is a method used to protect your customers\u2019 online accounts. In this process, users not only need to provide their username and password, but also a verification code as a second security measure. This verification code can be sent, for example, as an SMS to the user\u2019s mobile phone, and is therefore independent of the user\u2019s computer. Therefore, a potential attacker must obtain the password while simultaneously gaining access to the user\u2019s mobile phone. This makes a potential attack more difficult and significantly increases security, especially in the case of phishing attacks.<\/p>\n

What benefits does 2FA via SMS offer?<\/h2>\n

Two-factor authentication via physical devices such as a token generator, a card reader, or a USB key has the disadvantage that they always have to be carried by the user. With a mobile phone, this is already automatically the case and does not restrict the user\u2019s comfort. However, other devices are forgotten, and this can significantly complicate access. Additionally, these devices not only cost money due to the one-time purchase, but they also need to be replaced regularly.<\/p>\n

Two-factor authentication via SMS avoids these problems arising from physical use by sending a unique and non-reusable security code consisting of numbers or letters.<\/p>\n

Currently, there are also applications that allow customers to perform this double authentication via the app on their phone. However, these must be installed beforehand by the user. The user must learn to use these applications, and often problems arise when switching to a new mobile phone. The support effort cannot be underestimated. This applies especially to app compatibility due to the high number of different Android devices and versions.<\/p>\n

Instead, A2F allows anyone to receive this code via SMS with a range of more than 99%. For this reason, major internet companies such as Facebook, Instagram, Twitter, Gmail, Hotmail, Amazon, Dropbox, Google, and Microsoft offer the option to protect your account with this SMS authentication. Google itself offers an app for 2FA, but it mainly uses SMS itself.<\/p>\n

Furthermore, it forces your customers or users to always update their mobile phone number in your database, so that you can easily contact them on that number later as well.<\/p>\n
