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.

In today’s world, it feels like the technology changes faster than we can keep up. As technology becomes even more ingrained in our lives, it’s obvious, that for our own good, regulations need to evolve as well. And it’s extremely important that business owners and leaders understand new regulations to adapt in the best way possible.

Scrub customer databases and make SMS more effective

31 Oct 2017

It’s often that we are asked, “what is your average delivery rate in (fill in the blank) country?” People usually expect an answer like, “98%.” Yet cost efficiency and SMS conversion is more important than a percentage number; without context it doesn’t mean anything.

The more important question pertains to how delivery rates are calculated. Let’s point out that there are mobile operators in some countries that do not send delivery reports, or if they do, they are unreliable. Is the delivery rate statistic based on messages sent and the number of messages that received a “delivered" status? That is the most common and brutally simplified way to calculate delivery rate. First of all, in fact, it is best practice to start with clarifying whether or not the mobile number databases contain phone numbers that are deliverable.
