Don’t like dealing with a lot of usernames and passwords? The best part is that passwordless access to the internet is now a reality. You may soon be allowed to use fewer passwords for the online services you rely on often. If an application is passwordless, it indicates that user authentication is not based on a username and password.
As an alternative, users provide a cell phone number or mail address and are issued a one-time password or URL to use as verification during entry. In iOS 16 as well as macOS Ventura, the tech giant also introduced a unique service known as Passkeys. Passcodes leverage biometric authentication using Touch ID or Face ID as well as iCloud Keychain to synchronize securely across iOS devices, Macs, and Apple TVs.
Types of Passwordless Authentication
Passwordless authentication is safer and more convenient for customers. There are several methods to do this. Just a few examples:
The user inputs their email address, and an automated response is sent. The email will include a link that the user may click on to get an entry.
After entering a phone number, the program will automatically send a text message to that number. A one-time password is sent through text message, allowing the recipient access.
Personal characteristics, both bodily (such as in a fingerprinting or retinal scanning) and cognitive (such as in a personality test). In order to verify your identity before approving or rejecting your login attempt to an application or a website, Apple’s innovative Passkeys function makes use of Face Recognition or Touch ID.
Use of personal possession or another portable item as a means of verification. This might be a hardware token, a one-time password (OTP) obtained by text message, or the code created by a mobile authorization software.
Is Passwordless Authentication Safe?
Unfortunately, there is currently no foolproof method of authentication available. If by “secure” you mean “difficult to break” or “less vulnerable to the most frequent intrusions,” then passwordless security most certainly qualifies. Even while there seems to be no easy way in, even the most skilled cybercriminals could probably find a method to breach its security.
However, password-free methods are intrinsically more secure. As an example, a malicious agent might use any of the aforementioned methods (such as phishing, stolen passwords, sheer strength, etc.) to compromise a password-protected system. These kinds of assaults may be carried out by even inexperienced cyber criminals. However, gaining access to a system that doesn’t need a password requires a far greater degree of expertise and resources from a hacker.
