Passwords have long been used to protect online accounts. A password is a secret word or phrase that a user types in to prove their identity. Its safety depends on how strong it is and how carefully it is protected. Weak, reused, or shared passwords increase the risk of accounts being hacked or misused.
A passkey is a newer method of logging in that removes the need to remember or type anything. Instead of a secret word, a passkey is stored securely on a device such as a phone or computer. When logging in, the device confirms identity using a fingerprint, face scan, or device PIN.
The key difference lies in how security works. Passwords are sent to a website during login, which means they can be stolen in data breaches or through fake websites. Passkeys work differently. The actual key never leaves the device. The website only receives confirmation that the correct key was used.
Ease of use also differs. Passwords must be created, remembered, and updated regularly. Passkeys make logging in quicker, often requiring just a touch or glance. They also reduce human error because they cannot be reused across sites or typed into phishing pages.
Passwords are still common, but passkeys are being adopted to offer stronger, simpler protection in today’s digital environment.
