Passkeys are an easy and secure alternative to traditional passwords that can help prevent phishing attacks and make your online experience smoother and safer.
Unfortunately, Big Tech’s rollout of this technology prioritized using passkeys to lock people into their walled gardens over providing universal security for everyone (you have to use their platform, which often does not work across all platforms). And many password managers only support passkeys on specific platforms or provide them with paid plans, meaning you only get to reap passkeys’ security benefits if you can afford them.
They’ve reimagined passkeys, helping them reach their full potential as free, universal, and open-source tech. They have made online privacy and security accessible to everyone, regardless of what device you use or your ability to pay.
I’m still a paying customer of Bitwarden as Proton Pass was up to now still not doing everything, but this may make me re-evaluate using Proton Pass as I’m also a paying customer of Proton Pass. It certainly looks like Proton Pass is advancing at quite a pace, and Proton has already built up a good reputation for private e-mail and an excellent VPN client.
Proton is also the ONLY passkey provider that I’ve seen allowing you to store, share, and export passkeys just like you can with passwords!

I don’t like passkeys yet because they’re implemented poorly on most platforms, IMHO, because they replace two factors with one. Some don’t let you also turn on two factor auth at all which is dumb, but the ones that do then often only have options that use your device as a factor either through text or email. So if the passkey is your phone and you add text messages as the 2 factor option, that’s still your phone. Or if your passkey is your laptop and you’re logged into your email on the laptop, it’s just one.
Passkeys are 2FA
Could either you or @phoneymouse@lemmy.world explain this for me? If all that’s required to log in using a passkey is access to a single device/provider (e.g. Proton Pass in this case) how does it replace 2FA?
That’s because it’s not 2FA, strictly speaking. The second factor is whatever the device uses to verify you. So, essentially:
You go to a webpage, then go to sign up. Instead of inputting a password, you just input some ID, like a username or email. The device generates a cryptographic handshake with the webpage and your ID. You don’t (can’t, unless you can memorize a string of thousands of letters and numbers and be really good at math with prime numbers) have to remember it.
Now, when you go to login to that page again, the device just remembers and exchanges the keys with the webpage for you. That is NOT 2FA. But, you can configure your device to require another verification (most do). So, when you go to login, then the device asks you to use your fingerprint, or a remembered PIN. Or whatever that confirms that the one handling the device is indeed you before sharing encryption keys with the webpage. This is sorta 2FA, but not really because the webpage is delegating the second factor to the same device actually doing the login. Which might be compromised altogether, but that already happens with most 2FA implementations.
If you go to a second device, and wish to login, then your second device will fallback to other 2FA versions, like sending a OTP to the verified email or phone, or asking you to verify on the one device that is already logged in.
For an authentication flow to qualify as two factor authentication, a user must verify at least two factors - and each must be from the following list:
Passkeys require you to verify a password or authenticate with biometrics. That’s one factor. The second factor is having the passkey itself, as well as the device it’s on.
If you login to your password manager on your phone and use your fingerprint to auth, that’s two factors right there.
But authentication to access the passkey is on a remote device. So the server doesn’t have any information about if or how authentication was performed for the person to access the key. If they use a 4 digit pin or, worse, the 4 point pattern unlock, it’s easy enough to brute force on most devices.
This is also why using a password manager is not two factor authentication. It is one factor on your device and one factor on the server. But no one monitors the security logs on the device to detect brute force attacks and invalidate keys. Most don’t even wipe the device if the pin is being brute forced.
