What is OTP?
OTP is a 4-6 numeric or alphanumeric code with a single-use specific function for a particular session/authentication. In today’s age, it is pretty normal to have a double-factor authentication or even a multi-factor authentication. It ensures an added layer of security and prevents fraud and security theft. OTP was developed to serve the singular purpose of providing authentication and verifying users. It is used in quite a few businesses to maintain a secure and safe user flow. OTP is usually sent via an SMS, and they tend to expire after a certain amount of time – generally after 10 minutes. So as a business, you need to ensure that your customers instantly receive their OTPs and can log in/authenticate smoothly. For this, you need to choose an OTP service provider’s voice or SMS OTP verification service.
What is an OTP service provider?
An OTP service provider is any company or platform that helps you deliver OTPs to customers. The service provider may use SMS, email, or mobile apps. OTP service providers help businesses improve security by adding an extra layer of authentication to protect user accounts and sensitive information.
What features should I look for in an SMS OTP provider?
Here are the nine features you should look out for in an SMS OTP provider:
- Delivery speed and reliability: Reliability measures the percentage of outgoing SMS OTP that reach their intended destination. On the other hand, delivery speed measures the time between sending and receiving the SMS OTP. Both metrics offer valuable information on the deliverability of SMS OTP.
- High delivery rates: High delivery rates ensure your customers receive SMS OTP as soon as possible. Technically a 100% delivery rate is unachievable. Look for a rate as close to 100% as possible.
- High-level security features: Security features like single-time or time-limited use give SMS OTPs an edge over email authentication. SMS OTPs also give you an additional layer of security when used with passwords.
- Compliance with relevant regulations: Choosing SMS providers that mind compliance helps you abide by the laws of the land. Refer to your local regulatory body to learn about the general laws and regulations. Then ask your SMS provider how they apply them.
- Two-factor authentication: 2FA helps you secure your accounts by adding an additional layer of verification. Single-step verification can be hacked into, so having 2FA via SMS OTP is essential.
- Integration with third-party applications: OTPs are autogenerated. An OTP service provider that easily integrates with other applications makes life easy for you.
- Customer support: You will not be able to figure it all out by yourself. You will need to connect with your SMS provider when you hit a roadblock. A 24/7 support structure in addition to a knowledge base that you can refer to is ideal.
- Transparent pricing: While most pricing is displayed on websites, some cost structures may be hidden, like recurring monthly costs. These can significantly impact your operational costs.
- Flexible billing options: Compared to a fixed billing option, a flexible option lets you pay for the consumption. Look for pay-as-you-go options with SMS providers. This will drastically reduce your operational costs.
