User Authentication and What SMS Has To Do With It

- 5 MIN READ - 26 Jan 2014

Here at Messente we know how important it is to manage authentication within your applications, while keeping the logic clean and possibly automated.

Furthermore the need to improve secure authentication is often behind finding the balance between user-friendly and smart solution.

Traditional approach to security used to rely on using passwords and usernames to authenticate users and, despite the simplicity, also SMS can be an extremely valuable part in your security layer.

Two-factors when and where you need them

You have probably experienced two-factor authentication, also known as 2FA, when you last downloaded and tried one of the popular over-the-top (OTT) messaging app (such as WhatsApp, Viber, Line etc.).

Many of the applications would require more than a single password and two-factor authentication would involve using different factors simultaneously:
– something the user already knows (for example, a chosen password);
– something the user has (for example, a mobile phone);
– something the user gets (for example, a PIN code sent in an SMS message).

Combination of these significantly increases security, while SMS is an easy, reliable and straightforward way to deliver your authentication notifications.

How it works

In a simplified scenario, user enters the mobile phone number into the application’s form, receives authentication PIN code in an SMS message and types it into the application’s form to confirm the identity.

It’s fast. SMS notification is received at your handset in seconds and it won’t get in the way or slow you down.

It’s easy. Users are well familiar with SMS notifications, thus authenticating is straightforward and distinct.

It’s secure. SMS notification is generated and sent via other – non-email nor web – channel and application can compare the originally generated password with the submitted one.

Consider this in the bidding process - Part 2

16 Jan 2018

Continuing last week’s discussion around things that companies must consider when selecting a global SMS messaging partner through a formal request for proposal, or bid, here are three more critical variables to point out. Again, these are based on our experience of customers turning to us after they tried the lowest cost tender.

Personalized support and why there is no way around it

02 Jan 2018

We often see client support packaged into software products, whether it includes general support tickets, to live chat, to dedicated account managers. And it comes with a cost to the software publisher, which is often passed on to the clients. As product features expand, support tends to suffer, with reply times increasing, quality of support declining, and costs expanding to solve service issues quickly. Eventually, the personal touch of client support fades.
