That is to say: The more people use the web, the more folks with nefarious intent slip in—and the more you need protection.
This article provides a comprehensive comparison of some of best fraud prevention solutions for 2FA on the market today. We’ll take a look at Telnyx Verify API and its main competitors, including Twilio, Plivo, Sinch, Vonage, Bandwidth, and CM.com. We'll examine their features, pricing, ease of use, and overall effectiveness in combating fraud so you can protect your business.
Due to the increasing number of bad actors online, businesses are more vulnerable to fraud now than ever before. Cybercriminals are constantly developing new methods to exploit vulnerabilities, making it essential for companies to stay one step ahead. But fraud prevention is about a lot more than just knowing what a looks like. It’s a comprehensive, 360 process that takes into account many different channels of potential fraud and works to shore up potential exploits across the business.

What is two-factor authentication and how does it work? Two-factor authentication adds a second proof of identity on top of your password. That second factor can be a one-time code, a hardware security key, or a biometric check.
Why do some say 2FA is no longer safe? 2FA remains effective, but weak second factors and poor practices can undermine it, such as SIM swapping, OTP phishing, or writing recovery codes on tokens. Stronger factors and user education close most of those gaps.
What is the most secure 2FA method? Hardware security keys are the gold standard because they resist phishing and device compromise. Authenticator apps and push approvals are strong alternatives, while SMS is best kept as a backup.
Is SMS a good choice for delivering authentication codes? For reach and simplicity, the text-only protocol SMS works on nearly every device and network. It is more vulnerable to attacks like SIM swapping than app or hardware factors, so use it for low-risk scenarios or as a fallback.
Should businesses use MMS for two-factor authentication? Most organizations should not send one-time codes over because richer media adds payload and delivery variability without improving security. Use MMS for visual instructions or brand education, and keep OTP delivery to SMS or app-based methods.

Truly effective fraud prevention accomplishes two things:
Of course, you want to protect what you’ve built. But to sustain it, you’ll want to reassure people that their information will be safe with you. Feeling that you’re a trustworthy business will help you gain and retain more customers.
When we talk about fraud prevention and protection, we’re usually looking at several safety features. The best ones offer protection across a range of areas and often meld and merge with one another. Of these, 2FA is perhaps the biggest. Let’s take a look at what that means for you and how you can best utilize it.
2FA (two-factor authentication) is a critical tool for preventing fraud in 2024. It does just what the name implies: requires users to provide two different ways to prove they are who they say they are in order to access accounts or other information.
By requiring users to provide two forms of identification before granting access, 2FA adds an extra layer of security beyond just a password. The two factors typically involve something the user knows (like a password) and something the user has (such as a smartphone to receive a verification code).
In 2024, cyber threats have become more sophisticated. Passwords alone are no longer sufficient to protect sensitive information. With 2FA, even if a hacker obtains a user's password, they still need the second factor to gain access. Multiple factors make unauthorized access significantly more difficult. This requirement is especially important for protecting things like financial transactions, personal data, and business systems.
2FA started off with just using a regular password and a text notification that provided users with a code to enter, and some systems still work this way. However, the world of 2FA has expanded and become increasingly varied. Modern 2FA solutions include SMS-based codes, authenticator apps, and biometric verification, all of which enhance security while still being relatively easy for users. By leveraging 2FA, businesses can reduce the risk of data breaches and build trust with their customers, knowing that their accounts are safeguarded against unauthorized access.
Implementing 2FA is a proactive step towards robust fraud prevention, providing peace of mind for both businesses and their customers in an era of increasing cybercrime.
When choosing a two-factor authentication provider, several key factors should guide your decision:
Look for providers that offer multiple authentication methods, such as SMS codes, authenticator apps, and biometric options. Ensure they support the latest encryption standards and provide features like token expiration and device recognition.
The provider should offer comprehensive documentation, SDKs, and APIs to facilitate seamless integration with your existing systems. Check for compatibility with popular programming languages and platforms.
If a 2FA tool is too frustrating to use, it won’t do much to help maintain security. A good 2FA provider should offer a user-friendly experience, with easy enrollment and authentication processes. Features like self-service password reset and user management can enhance usability.
Ensure the provider can handle high volumes of authentication requests and has a robust infrastructure to guarantee uptime and reliability. Look for providers with a proven track record in scalability. Even if your business is small now, it’s likely to scale, so find tools that can keep up.
Verify that the provider complies with relevant regulations and standards, such as GDPR, CCPA, and PCI-DSS. Complying with these regulations is crucial for protecting user data and avoiding legal issues.
Consider the pricing model and ensure it aligns with your budget. Look for transparent pricing with no hidden fees or sneaky upcharges.
Reliable customer support is essential. Depending on your needs and how your team is likely to use the support, check if the provider offers 24/7 support and additional resources like knowledge bases and community forums.
Choosing the right 2FA provider involves balancing security, ease of use, and cost. Evaluating these factors will help ensure you select a provider that meets your specific needs and enhances your overall security.
So what tools meet all of the above requirements? While every business will have a unique set of needs, we’ve pulled together the tools we think are the absolutely best-in-class options for 2FA solutions. We’ll go into more detail below, but here’s a quick ranking system to help you identify what options might be best for you at a glance.
| Sinch | SMS, voice, email | High delivery rates, direct carrier connections, real-time analytics and reporting | Competitive pricing, volume discounts available. |
| Vonage | SMS, voice, | Global reach, detailed reporting, direct carrier connections | Competitive pricing, clear rates. |
| Bandwidth | SMS, voice, | Direct-to-carrier messaging, high reliability, comprehensive analytics | Cost-effective solutions, transparent pricing. |
| CM.com | SMS, voice, email | High delivery rates, advanced analytics, direct carrier connections | Competitive pricing, varies by method and region. |
What risks threaten 2FA and how can we mitigate them? Common risks include phishing, SIM swaps, device theft, and recovery-flow abuse. Mitigate with phishing-resistant keys, number-port-out protections, device attestation, rate limits, and secure recovery options.
How should an enterprise roll out a 2FA solution at scale? Start with risk-based policies that prefer hardware keys or push, provide backup codes, and migrate users in phases with clear comms and self-service recovery. Align user notifications to the right messaging types and channels, and monitor enrollment, success rates, and support tickets to iterate.
