Passwordless authentication is a much more secure and effective way to protect your and your users' accounts. Let's review each authentication method to understand how they can help keep data safe.
Single Sign-On (SSO)
Single-sign-on SSO is the most common method of passwordless authentication. It allows users to securely log in to third-party applications using a single set of credentials. Almost all of us have logged in with services from Google, Microsoft, Facebook, Slack, and others as SSO.
SSO saves users from having to authenticate repeatedly. Users find effective a complete list of unit mobile numbers list this very convenient as they can retain a valid session across all SSO-enabled applications by logging in once.
Biometrics
Biometric authentication verifies a user's identity using physical or behavioral characteristics. Biological factors include:
Fingerprint recognition
Facial recognition
Voice recognition
Iris Scan
To set up an account, the user must choose one or more of the above physical characteristics, which are then stored in a database. To access the account, the user's characteristics are compared to the data stored in the database. Verification occurs when the match is successful and the user logs into the account.
Biometric identification is used to simplify the user experience with systems. The method is more secure because the probability of identical fingerprints, face or iris is very low. Various types of security-conscious applications and devices such as those related to banking, schools, healthcare, mobile phones and more use biometric authentication methods to authenticate.
Possession factors
Possession factors grant users access through something they own/possess, such as a mobile device. Users can receive a one-time passcode (OTP) via email or SMS. Users are then automatically logged into the system by responding to notifications or entering the codes.
Attacks are less likely to occur in this case because attackers need the possession factor to respond to application requests.
Magical Links
Magic Links allow users to authenticate without a password. The user is prompted to enter their email address. The system then sends a unique URL to the email. Once the URL is opened, the user can log into the app or account.
