Is passwordless authentication safe?

Passwordless authentication methods are becoming increasingly popular as a means to quickly and safely login to accounts.

Passwordless authentication differs from traditional methods by not requiring users to input a password. Instead, it uses features like biometrics, one-time codes, or security keys for verification.

Learn about passwordless authentication, its possible benefits, and security considerations.

What to know about passwordless authentication

Passwordless authentication is a method of verifying a user's identity without requiring a password. Here are some common passwordless methods:

• Fingerprint and facial recognition biometrics. Biometrics use unique physical traits, such as fingerprints or facial features, to verify identity.
• One-time codes sent via SMS or mobile app. A temporary code is sent to the user's device, which they then enter to complete the login process.
• Security keys. These are physical devices that generate unique authentication codes for each login attempt.
• Passkeys. Passkeys are digitally stored on the user's device and provide seamless and secure authentication.

Potential benefits of passwordless authentication

Passwordless logins are a safe and secure way for users to log in. Potential benefits include:

• Increased security. The risk of password theft or brute-force attacks can be reduced by removing passwords from the authentication process. This decreases the potential for hacking and unauthorized access.
• Convenience. Passwordless authentication can provide a fast and easy login experience without the need to remember or manage passwords.
• Comfort level. Some users may feel more comfortable using biometrics (like fingerprint or facial recognition) and others may want to receive one-time codes via SMS or mobile app. The various options allow users to choose what they feel suits their login needs and preferences.

Security and safety considerations

While passwordless login methods may enhance security, there are important considerations to keep in mind.

It's important to use additional authentication, like MFA, alongside the chosen passwordless option. An additional verification factor can provide an extra layer of security, making it harder for unauthorized users to gain access.

It is also important to ensure that providers of passwordless authentication methods have strong security measures in place.
