Passwordless authentication
Passwordless authentication lets you log in using something else, like a phone or a security key, instead of a password.
A method of verifying a user's identity without requiring a password. Instead of typing a password, users might use a biometric scan, a code sent to their phone, or a hardware key. This approach reduces the risk of passwords being stolen or guessed.
What it means
Passwordless authentication replaces traditional passwords with other forms of verification. These methods are often more secure because they are harder to steal or guess. For example, a phone app might generate a one-time code that you enter instead of a password.
Why it matters
Passwords are a common target for hackers. If a password is stolen, it can lead to account theft or data breaches. Passwordless methods reduce this risk by using unique, device-specific verification steps that are harder to replicate.
What to do
If you're considering passwordless authentication, look for services that offer options like biometrics, one-time codes, or security keys. Make sure these methods are supported by your apps and websites. Always use trusted devices and avoid sharing your verification methods with others.
