And unfortunately, attackers have become extremely good at stealing them.
A major change is now happening in digital identity: the move toward passkeys and passwordless authentication.
What Is a Passkey?
A passkey is a modern method of authentication designed to replace traditional passwords.
Instead of typing a password, users can authenticate using mechanisms already available on their devices, such as biometrics or device authentication.
The technology is designed to make authentication both easier for users and more resistant to common phishing attacks — replacing methods such as passwords, email codes, and SMS codes.
Why Are Passwords a Problem?
Passwords create several problems. People often reuse them. They choose weak ones. They store them insecurely. Attackers create fake websites designed to steal them.
Even technically strong passwords can sometimes be captured through phishing.
Organisations therefore spend considerable effort managing password policies, password resets, multifactor authentication, and identity security. Passkeys attempt to improve this model.
Passwordless Is Moving Into the Mainstream
This is not only a theoretical cybersecurity trend. Major identity providers are making passkeys the default authentication experience rather than an optional extra, and passkey availability continues to expand across operating systems and customer-facing identity systems.
That tells technology professionals something important: passwordless authentication is moving from experimentation toward mainstream enterprise use.
Does Passwordless Mean Security Becomes Easy?
No. Removing passwords solves certain security problems, but identity security remains complex.
Organisations still need to think about:
- Account recovery
- Device security
- Identity verification
- Access control
- Session security
- Fraud
- Lost devices
- Privileged accounts
A secure authentication system is more than just the login screen.
Why QA Engineers Should Care
Authentication is one of the most important areas of application testing. A tester working on passwordless systems may need to validate:
- Registration
- Passkey creation
- Login
- Multiple devices
- Recovery
- Account lockout
- Browser compatibility
- Authentication failures
- Security requirements
This makes cybersecurity knowledge increasingly useful even for professionals who do not have “Security” in their job title.
Why Developers Should Care
Modern developers frequently build applications that interact with identity providers. Understanding authentication, authorisation, tokens, OAuth, multifactor authentication and passkeys can make developers much stronger at building secure systems.
Cybersecurity Is Becoming Everyone’s Responsibility
Security is no longer a separate step performed after software development is finished. Developers, testers, DevOps teams, cloud engineers, and platform teams increasingly need to understand security throughout the development lifecycle.
Passkeys are one example of how quickly this area continues to evolve. The login experience we have used for decades may gradually become much less dependent on passwords.
Security skills are useful in almost every technical career.
