Benefits of 2-factor authentication

Secure your services

Two-factor authentication (also known as 2-step verification) safeguards apps and online services from malicious attacks, fraud, and data loss

Protect your users

Even strong passwords are hackable, which is why two-factor authentication, or 2FA, provides a second layer of control to eliminate unauthorized access to the accounts

Better customer satisfaction

Show you care by ensuring the safety of the data your customers share with your app or online service


How 2-step verification works


2FA - 1st step of verification

The user enters their username and password into a login form


Passcode delivery

Apico SMS API automatically sends an SMS text message with a passcode to the user's cell phone


2FA - 2d step of verification

The user inputs that passcode on the webpage to complete the transaction


to complete the transaction

2FA requires the correct combination of one-time passcode + password


Out-of-band authentication

One-time SMS passcodes for 2FA are delivered over a mobile network as a second, non-web/email, channel to make sure access to the accounts is secure

No need for a dedicated token

No additional device or software is required for mobile 2FA: a one-time code is delivered by SMS to the user's personal cell phone

Easy to implement

Mobile 2-step verification can be easily added to any web service or software application using Apico SMS API
