In 2022, passkeys emerged as a more secure authentication alternative to traditional passwords. It was that year that tech giants like Apple, Google, and Microsoft partnered with the FIDO Alliance to replace traditional passwords, which were often weak and easily hacked. Passkeys quickly became the gold standard for authentication in the security world. In the last four years, more and more businesses and individual users have adopted passkeys. Unfortunately, misconceptions about the use and how they work still persist in the industry.
Passkeys are secure replacements for passwords that use cryptographic math instead of typed text. When you make a passkey, your device creates a matched pair of digital keys. One key goes to the website, and the other stays locked on your device. While it may sound fairly straightforward, many are still confused about the usage and how they do and don’t work. Let’s take a look at 5 of the most common misconceptions about passkeys to clear the air about this security tool.
Myth #1: Stolen Devices or Site Hacks Compromise Passkeys
This is the most common passkey myth, and it stems from how we think about passwords. With a password, you and the website both hold a copy of the same secret string of text. If the website's database gets hacked or your phone is taken, your password is stolen.
Passkeys rely on cryptography (a pair of mathematically linked keys). The website only holds your public key, which acts like a lock that is completely useless to a hacker if stolen. Meanwhile, your private key acts as the physical key and never leaves the secure hardware of your personal device. Because this private key is never transmitted over the internet, hackers have no way to intercept it or breach your account. Even if someone physically steals your phone, they cannot use the private key without passing your device's security barrier (your biometric scan or device PIN).
Myth #2: Passkeys Share Biometric Data
It is a common misconception that companies like Google or Amazon are harvesting your biometric data when you set up or use a passkey. This confusion arises because the login process typically triggers your device's Face ID, Touch ID, or Android fingerprint scanner.
In reality, your biometric data is strictly confined to your device's local secure hardware enclave. The website or company never sees, receives, or stores your physical biometric information; they only receive a digital confirmation that your device successfully verified your identity.
Myth #3: Passkeys Can Be ‘Phished’
Unlike passwords, passkeys are mathematically impossible to guess. Because they require your device to physically sign into the exact site you registered with, fake phishing websites cannot trick you into handing them over.
Myth #4: All Passkeys Are the Same
The term "passkey" actually covers two different setups. First, there are synced passkeys, which back up to the cloud (like Apple or Google) so you can easily access your accounts across different devices or recover them if your phone is lost. Second, there are device-bound passkeys, which are permanently stored on a specific physical device and cannot be copied. While synced passkeys offer the perfect balance of convenience for everyday users, device-bound passkeys provide the ultra-strict security required by high-stakes business and corporate environments.
Myth #5: A Single Passkey Covers all Sites & Accounts
A single passkey isn't a master key that can unlock all of your online accounts. You’ll still need to create a passkey for each online account. That might sound a little tedious, but in practice, passkeys are incredibly convenient to create, store, and use.
While lingering misconceptions about passkeys may cause users to hesitate, the reality is that they offer an unparalleled combination of security, privacy, and convenience that traditional passwords simply cannot match. Transitioning to a passkey-based authentication model is an essential step for any organization looking to future-proof its defenses and mitigate the risks posed by modern cyber threats.
