What is OTP ? 

One Time Password (OTP) is a service developed by Octopush that allows you to manage the authentication of your service without having to write a single line of code. We take care, as a trusted third party, of the management of the double authentication for you. Immediate time savings and enhanced security.

We send an automatically generated one-time numeric or alphanumeric code by SMS or voice SMS. This code is valid for a short time and for a single login or transaction session. The user then receives the OTP code on his phone and enters it on the device where the authentication takes place via our API.

Frequently Asked Questions
What does OTP mean?

OTP means One Time Password: it’s a temporary, secure PIN code sent to you via SMS valid for one session.

How does OTP work?

One-time passwords are based on an algorithm that creates a new and random code each time a password is requested. But to fully understand how an OTP works, there are two components to consider: the OTP generator and the authentication server

Is OTP a 2 Factor Authentication?

One-time passwords (OTPs) are an authentication method commonly used as part of two-factor identification (2FA) and multi-factor authentication (MFA) that can help balance these needs.

How does OTP generator work?

OTP generation algorithms typically make use of pseudorandomness or randomness to generate a shared key or seed, and cryptographic hash functions, which can be used to derive a value but are hard to reverse and therefore difficult for an attacker to obtain the data that was used for the hash.

Is OTP secure?

An OTP is more secure than a static password, especially a user-created password, which can be weak and reused across multiple accounts. OTPs may replace authentication login information or may be used in addition to it to add another layer of security

What is MFA and 2FA?

Multi-Factor Authentication (MFA) is a type of authentication that requires two or more factors of authentication. Two-Factor Authentication (2FA) is a type of authentication that requires exactly two factors of authentication

Every Two-Factor Authentication is Multi-Factor Authentication buy Not every Multi-Factor Authentication is Two-Factor Authentication

Can I send OTP via voice?

Yes, you can do this very simply by just using a switcher and enabling SMS via voice.

Can I personalise the sender?

Yes, but you must know that this option is not always available. It depends on the country and mobile network of the recipient.

What are confusing characters?

Sometimes some characters can be confusing and create frustration for the user. You can simply remove these symbols while creating OTP using our generators. One example that will help you understand confusing character are the number zero and letter “o”: ‘0,O’
