Passwords have long been the cornerstone of digital security—but they’re also one of its weakest links. With phishing, credential stuffing, and brute-force attacks on the rise, many organisations are exploring passwordless authentication as a more secure and user-friendly alternative.
But is going passwordless right for your business? Let’s explore the benefits, challenges, and what it takes to make the switch.
The Pros of Going Passwordless
1. Enhanced Security
Passwordless authentication eliminates the risk of password theft, reuse, and phishing. Since there’s no password to steal, attackers have fewer entry points
2. Improved User Experience
Users no longer need to remember complex passwords or reset forgotten ones. Biometric logins or device-based authentication streamline access and reduce frustration
3. Reduced IT Support Costs
Password resets are one of the most common helpdesk requests. Going passwordless can significantly reduce support tickets and associated costs
4. Faster Authentication
Biometric or token-based logins are often quicker than typing in a password, especially on mobile devices
5. Better Compliance
Passwordless systems can help meet compliance requirements by enforcing stronger authentication without relying on user behaviour.
The Cons of Going Passwordless
1. Complex Implementation
Transitioning to passwordless requires changes to infrastructure, identity providers, and user workflows. It’s not a plug-and-play solution
2. Higher Upfront Costs
Deploying biometric scanners, security keys, or mobile authentication apps can be costly, especially for large organisations
3. User Resistance
Some users may be hesitant to adopt new methods, particularly if they involve biometrics or unfamiliar devices
4. Troubleshooting Challenges
When something goes wrong—like a lost device or failed biometric scan—support teams need new protocols to resolve access issues
What’s Involved in Going Passwordless?
1. Assess Your Environment
Start by identifying where passwords are used across your systems—email, VPN, SaaS apps, internal portals—and evaluate the risk and feasibility of replacing them.
2. Choose Your Authentication Methods
Common passwordless options include:
- Biometrics (fingerprint, facial recognition)
- Hardware tokens (e.g. YubiKey)
- Mobile push notifications (e.g. Microsoft Authenticator)
- Passkeys (FIDO2/WebAuthn standards)
3. Update Your Identity Infrastructure
You’ll need an identity provider (IdP) that supports passwordless protocols like FIDO2, SAML, or OAuth2. Integration with your existing systems is key.
4. Pilot and Train
Start with a small group of users to test the new system. Provide training and support to ease the transition.
5. Phase Out Passwords
Gradually disable password-based logins for systems that support passwordless. Maintain fallback options during the transition.
6. Monitor and Optimise
Track adoption, user feedback, and incident rates. Adjust policies and support as needed.
Going passwordless isn’t just a trend—it’s a strategic move toward stronger, simpler, and more secure authentication. While the transition requires planning and investment, the long-term benefits in security, usability, and cost savings can be substantial.
