Passkeys are the latest, and some say greatest, account security mechanism, but many users remain confused about the technology.
Well-known tech writer Leo Notenboom recently published an article titled How Passkeys Work (A No-Tech Version), which is perhaps the best and easiest-to-understand explanation I’ve seen. However, the majority of comments from Leo’s readers prove that many users are still struggling to grasp the passkey concept.

Here then are some of the main points of confusion about passkeys clarified in the simplest of terms:
- Passkeys Are Per Device: Passkeys are saved on the device on which they are created, and the passkey will only work on the device on which it is created
- Passkeys & Password Managers: Using a cloud-based password manager, such as Bitwarden, will allow for passkeys to be shared across devices. However, the same password manager must be used across all devices
- Passkeys & Passwords: Creating a passkey does not mean that a password previously created for that account will no longer work; both are valid. The only way a password will become superseded by a passkey is if the service/website itself stops accepting passwords, and passkeys then become the only option
Passkey Pros:
Enhanced Security:
- Encryption: Because it’s encrypted, a passkey cannot be viewed or guessed by anyone
- Breach Protection: Passkeys protect the user in cases of external data breaches because the private key – which allows access to the account — never leaves the device
Passkey Cons:
- Lost or Stolen PC: If a PC is lost or stolen and the person now in possession manages to gain access to the system, then that person will also have free access to all your accounts. You need to ensure that access to the system is protected by a strong security measure, such as a very strong password, PIN, or biometrics
- Fresh/Clean Installs: If you perform a fresh/clean operating system install, all passkeys will be lost unless they are stored in a password manager
BOTTOM LINE:
The underlying problem is that the passkey technology is complex and evolving, which does make it very difficult to explain, let alone to understand. Heck, even I am not altogether comfortable with the concept.
That said, it seems passkeys are the way of the future, so I guess we’ll all eventually need to get on board. In the meantime, I’ll stick with a strong password together with 2FA.
How about you? Are you into passkeys or just as confused as many users appear to be?

Jim, I have read extensively on this passkey thing and now many sites are pushing for its use. I am one of the many still confused. I run a system where I use multiple browsers on there devices and use multiple email addresses to segregate different interests. From what I can see, this passkey thing works if I use the same email address on each device and run just a single browser.
Why can’t they run passkey outside the browser so it can be used with multiple browsers and devices?
“From what I can see, this passkey thing works if I use the same email address on each device and run just a single browser.”
No, that’s not correct Tom. You can have as many email addresses and use as many browsers on as many devices as you like.
Passkeys are stored outside the browser Tom, they’re actually saved in Windows’ secure credential storage. The browser only stores a reference to the passkey, acting as a sort of index, not the actual storage vault.
Password managers work in the same way as a browser’s built-in password manager but are generally considered to be more secure.
Because you’re using multiple browsers, it would not be convenient for you to save passkeys in the browser’s password manager, your best bet would be to use a password manager.
Most password managers, including the Bitwarden and Proton Pass free versions, include browser extensions for all mainstream browsers. You install the password manager extension in each browser on each device and the passkeys will then be synced and available in all browsers across all devices.
It is confusing, I know. When one gets down to the nitty gritty, there’s a lot of technical jargon involved, but I hope my simple explanation here helps.
