FAQ

OTP and two-factor authentication FAQs

How mblastr delivers One Time Passwords over SMS and voice.

How does the mblastr OTP service work?

mblastr delivers a One Time Password to the user's mobile phone over an out-of-band channel - SMS or a voice call - so the phone becomes a second factor of authentication alongside the password. This protects customer accounts from takeover and data theft.

Which channels can OTPs be delivered on?

Two channels: SMS and voice call. Voice is a useful fallback when an SMS does not arrive or when the user prefers to hear the code.

How do I integrate OTP into my application?

Integrate with the mblastr OTP PUSH or Redirect REST API. Both give secure login to your customers' data and resources without you building or maintaining any telecom infrastructure.

Why send One Time Passwords over SMS?

SMS has roughly a 98% open rate within 30 seconds, which makes it highly reliable for time-limited codes. It also reaches users who have no internet access at that moment.

Does OTP verification cost extra to run securely?

No. mblastr OTP verification lets you achieve two-factor security without additional associated costs, because there is no separate authentication infrastructure to license or host.
