Passwordless authentication refers to verifying the identity without using the traditional password. Instead of using passwords, this verification can include other methods like fingerprints, facial authentication, iris scans, and more. Also, there is a one-time code that is sent to the email and is used once to log into the account. Its purpose is to make things easier and quicker for the users. Such authentication methods are better because it is difficult for hackers to steal. Passwordless authentication relies on something you know, something you have, and something you have.
Evolution of Verification Methods
Early authentication methods only use passwords. There was a secret word or phrase that is remembered to get access to the accounts. There was no other way of authentication introduced. With time, people realized that it is easy to steal passwords and so it is not the authentic and secure way of verification.
Moreover, two-factor authentication was introduced in which the system sends a code to verify the identity. This adds an extra layer of security to the systems. After login to the account, temporary codes are generated to access particular accounts.
Furthermore, as technology evolves, passwordless verification systems are introduced. These are more secure and authentic. Methods like fingerprints, iris scans, face recognition, and others are some of the systems that contribute to this type of verification.
How Does it Operate?
This authentication relies on several technologies. These technologies mainly include biometrics, push notifications, magic links, one-time passwords, WebAuthn, and FIDO2.
- Biometric Authentication
It includes fingerprint verification, face recognition (password-face authentication), iris scan, voice recognition, DNA match, retina scan, and hand geometry. These verifications work by scanning the particular areas and the system will verify by comparing the features with the existing database. If there exists a person with similar features, then the system grants access to that individual.
- One-Time Password
OTP is a one-time code sent to the mobile phone or via email after entering the password. The system asks for the username and email address on a website. Then a code is received via SMS, email, or an authentication app. The received code is then applied to the website or app for verification. This code is only valid for a short time, no one can steal it.
- Magic Links
A magic link is a one-time-use link sent to an email. By clicking on the link, one can get access to the account without entering the password or PIN. It is an easy and quick way of verification.
- Push Notifications
These notifications confirm the login by sending a message to a mobile phone or any device. It asks if the person is trying to log in to the account. In this way, the owner will come to know the anonymous logins to the personal account. After entering a username or email on the website, the person will get a push notification. It requires the approval of the owner to log in to the account.
- WebAthn and FIDO2
These are the two methods of passwordless verification. It requires a small hardware key or a device like a USB. After setting up the system on devices like phones, while logging in the system secretly verifies your identity and allows access. These technologies are very secure because they use cryptographic keys that are nearly impossible to steal or guess.
Implementation of Passwordless Verifications
This technology is being used in a wide range of industries such as banks, smart devices, e-commerce, social media platforms, corporate use, remote access, healthcare, government, and more.
- Online banking is using this technology to make an effective and secure use of financial apps.
- This technology helps improve user’s experience and security in e-commerce.
- Social media platforms like Twitter, Instagram, and others containing personal information are using this verification method.
- Many corporate buildings are using this system in their biometric verifications.
- This authentication method is also helpful for those who work remotely. They do not need to be physically present to get verified by the system.
- Government organizations also use this type of verification method to protect the personal information of the citizens.
Conclusion
Face verification, fingerprints, iris scans,s and others are a step towards a safer and simpler way of verification. Despite the challenges and privacy issues, it is gaining fame in several industries because of its convenience. Over time, it will likely improve and advance in terms of more security and user adoption.
