Frequently Asked Questions
Find answers to the most frequently asked questions about our platform, its features, and how to use it here.
What is an SMS OTP?
An SMS OTP (One-Time Password) is a single-use verification code sent via text message. Randomly generated and valid for a limited time (typically 5 to 10 minutes), it is used to confirm a user's identity during logins, payments, or account verifications. It is the key mechanism for strong SMS-based authentication.
What is the difference between SMS OTP, 2FA, and MFA?
SMS OTP is the technical method (a code sent via text message). 2FA (two-factor authentication) and MFA (multi-factor authentication) refer to the security method that combines multiple identification elements. SMS OTP is one of the most widely used factors in a 2FA or MFA strategy, thanks to its simplicity and universality.
How long does it take for my user to receive the OTP code?
With Octopush, OTP SMS are delivered in under 10 seconds in the vast majority of cases, thanks to our direct routing to mobile carriers. Our deliverability rate exceeds 99.5% in France and over 200 countries.
Is SMS OTP compliant with GDPR and PSD2?
Yes. Our infrastructure is ISO 27001 certified and hosted in Europe. SMS OTP meets the Strong Customer Authentication (SCA) requirements mandated by the PSD2 directive, and our data is processed exclusively in Europe in accordance with GDPR. We also follow the recommendations of the ANSSI.
Can I customize the sender name?
Yes, you can set a custom sender name (e.g., "MyApp" instead of a short code) to build user trust and increase open rates. This option is available in most countries.
How much does it cost to send an OTP SMS?
Messages are billed individually, with no subscription required or setup fees. Check our pricing page for rates by destination. Volume discounts are available for high-volume senders.
