Hackers target companies that rely solely on passwords. Authenticator apps can stop them in their tracks.
Cybercrime is getting more sophisticated — and expensive. Cybersecurity Ventures estimates global cybercrime costs could approach $12 trillion annually by 2030. That kind of exposure is hard to ignore, especially if your systems still rely on passwords alone. Adding multifactor authentication (MFA) is one of the simplest ways to help protect your business. MFA doesn’t replace passwords; it adds another step before access is granted. And that extra step can make all the difference: Microsoft reports that 99.9 percent of compromised accounts lacked at least one additional verification method.
Authenticator apps power that second layer. They generate one-time passcodes users must enter before accessing company accounts or systems, helping prevent stolen credentials from turning into full-scale data breaches. We’ll explore six top-rated authenticator apps to help you choose the best fit for your business. Many are part of broader identity management platforms, which may also be worth considering, depending on your security needs.

Businesses can use Twilio’s authentication tools to secure employee logins and protect customer accounts. Authy is Twilio’s authenticator app for generating time-based one-time passwords (TOTP), while Twilio Verify powers SMS, voice, push and other verification workflows through its API.
Twilio’s usage-based pricing makes it attractive for businesses that prefer to pay per authentication event instead of per user. That structure can work well for companies with fluctuating login activity or seasonal spikes.
It’s also well-suited for e-commerce website security and subscription-based websites. You can require authentication when users log in from a new device, reset credentials or update payment details. Because pricing is tied to verification events, costs scale with actual usage, helping you control your cybersecurity budget. Think of it like paying for postage only when a letter is successfully delivered, not for every envelope you buy.
Twilio’s flexibility is one of its biggest strengths. Businesses can customize how authentication works and choose from multiple verification methods, including:
Other notable features include:

WatchGuard regularly updates its AuthPoint software for different platforms. Source: WatchGuard
WatchGuard AuthPoint is an authentication platform that helps secure logins to corporate computers, VPNs and cloud applications. It’s part of WatchGuard’s broader cybersecurity ecosystem, which includes firewalls, patch management, DNS-level protection and secure business Wi-Fi.
We like how the centralized dashboard lets IT teams manage AuthPoint alongside other WatchGuard services. Instead of switching between separate tools, administrators can control authentication policies from one place. From the dashboard, you can define which verification steps users must complete and configure features like single sign-on (SSO). With SSO enabled, employees can access multiple applications — such as Zoom and Salesforce — with one login instead of juggling separate passwords.
AuthPoint is a strong option for midsize organizations and businesses with distributed teams that need consistent security controls across locations.

LastPass has a user-friendly interface and an intuitive control panel. Source: LastPass
LastPass Adaptive MFA provides multiple authentication options to protect your company’s internal systems, cloud applications and business tools. Adaptive MFA is bundled with LastPass password management plans rather than sold as a standalone MFA product.
The platform includes the LastPass Authenticator app, which delivers one-time codes and push notifications for secure logins. You can also enable identity verification through device-based checks, biometrics (such as fingerprint or facial recognition) and hardware security keys, including YubiKey and Feitian devices.
We like the emphasis LastPass places on user experience. The platform is accessible to both technical and nontechnical employees. It also uses end-to-end encryption to help protect data in transit between users and LastPass’s servers.
LastPass can be a strong value if you want a companywide password manager with built-in MFA. However, if you’re only looking for a dedicated MFA solution, there are more affordable standalone options with fewer bundled features.

Cisco Duo is easily accessible across a variety of platforms. Source: Cisco
Cisco Duo is designed to simplify multifactor authentication. The apps download quickly and are straightforward for employees to use.
The admin interface is similarly easy to navigate. Whether you’re adding new users or defining which verification methods employees must complete to access corporate networks, cloud applications or VPNs, controls are centralized in one dashboard. Administrators can monitor device security at an individual level, configure SSO policies and enable biometric or passwordless authentication. The dashboard also shows who is logged in, which devices they’re using and whether those devices meet company security requirements.
Higher-tier plans include advanced features such as risk-based authentication, threat detection and zero-trust access controls. Duo is a strong option for businesses of all sizes that want robust MFA protection without an overly complex setup process.

Okta’s Workforce Identity platform is a highly secure option for businesses that need to protect logins for employees, contractors and strategic partners. The Okta Verify authentication app is especially powerful out of the box; it connects to over 7,000 pre-built app integrations, covering both cloud-based and on-premises software. This can save IT teams a significant amount of setup time.
Okta Verify supports passcodes, biometrics, push notifications, one-time passwords and SMS and QR-based verification. One standout feature is FastPass, which can verify a trusted device and may eliminate the need for passwords entirely.
Okta is also known for its free password manager, which provides strong protection for individual accounts. But, for business use, we especially like the Workforce Identity platform, which represents a big step forward in user verification. A key advantage is adaptive MFA, which adjusts the level of verification required based on factors like user behavior, login location and device health. Organizations can also implement phishing-resistant technologies like hardware keys and smart cards as part of their MFA rollout — essential for defending against social engineering attacks.
Okta Workforce Identity is on the pricier side, but it offers a few standout capabilities, including workflow automation. For example, it can automate identity workflows and sync verified user data with connected systems like CRM platforms. It’s definitely worth shortlisting, though budget-conscious businesses may find better value with other platforms.

RSA SecurID offers strong protection for businesses with on-premises, hybrid and multicloud environments. Through the RSA Authenticator app, users can log in using various methods, including FIDO passkeys (mobile keys stored on smartphones or security keys), biometric verification, QR codes, one-time passcodes, code matching and app-based push approvals.
We were impressed by the system’s intelligence. It learns user behavior and device patterns, helping reduce unnecessary login prompts while still triggering extra verification when something seems off. We also liked the platform’s strong offline capabilities and the robust support available through RSA and its global partner network.
This flexible, easy-to-use system is a smart choice for medium and large enterprises. However, the platform’s extensive feature set may be more than most SMBs need — and it may come with a higher price tag than they’re looking for.
