YubiKey? Ever? No? Hello?
The dedicated Protonmail community deserves a real response from the crack team of Protonmail scientists and engineers. When are you implementing Yubikey or are is your tag line just bs?

There's no need to be rude.

Would propose to change the subject title to "U2F/FIDO2 support". Would be more appropriate, especially crucial when we would like to stick with free and open-source software, standards, etc. There is certainly FIDO Alliance at https://fidoalliance.org/ where these new standards are available. Nowadays FIDO2 https://fidoalliance.org/fido2/ , https://en.wikipedia.org/wiki/FIDO2_Project is used. In general, we are speaking about HSM (https://en.wikipedia.org/wiki/Hardware_security_module , https://www.cryptomathic.com/news-events/blog/understanding-hardware-security-modules-hsms) support with nowadays standards, currently FIDO2 and from former times also U2F (https://en.wikipedia.org/wiki/Universal_2nd_Factor). Today we have also CloudHSM (e.g. Amazon https://aws.amazon.com/cloudhsm/ , Google https://cloud.google.com/security-key-management , IBM https://cloud.ibm.com/catalog/infrastructure/hardware-security-module), but also software defined HSM, e.g. Krypton (U2F, https://krypt.co/ , https://alternativeto.net/software/krypton/).

Love ProtonMail. Even have the paid version. Hate not being able to use my YubiKey for 2FA with ProtonMail. C'mon guys! Get with it!

YubiKey is not as safe as open source alternatives like Solo, but yes, I want U2F/FIDO2 support.

Aerion commented
This is essential. It's the only 2FA method that
1) doesn't require a mobile phone with a charged battery and a working mobile signal and/or internet connection
2) doesn't require drivers
3) doesn't require a special app
4) protects against man-in-the-middle attacks
5) is incredibly easy to take with you
6) you are likely to always have with you since you leave the house with your keys (right?)
7) is insanely quick and easy to use
8) doesn't pose any risks if you were to lose it since it's not tied to your person, identities, or accounts
9) is durable
10) works anywhere: USB-A, USB-C, Lightning, and NFC
11) you can have a backup of (most services, except Twitter, support registration of multiple U2F keysWhy this is still not supported is beyond me.

FIDO2 U2F is a running joke with ProtonMail, I doubt they will ever support it.

This should be consolidated with request for FIFO2 U2F Security Key Support for MFA (https://protonmail.uservoice.com/forums/284483-protonmail/suggestions/36590311-fifo2-u2f-security-key-support-for-mfa). U2F would allow for Yubikey and other standards supporting 2FA devices to be used.

I'd like to see this expanded BEYOND Yubikey to FIDO2... Any USB security key should work as a U2F. Please.

Dont understand how u2f is still not supported - literally boggles my mind.

Search results for this tell the story Coming Soon(tm) since 2015!

Lastpass failed to deliver on U2F, so I failed to renew with them. The single line item preventing me from going with a visionary subscription is yubikey/u2f support. I am sure there are many others in my shoes. It has been years of "coming soon". Get it done already! Thanks!

Please, we need FIDO U2F ASAP. This is a very important feature.

It would be nice to add FIDO1/FIDO2 authentication.
My problem with Google Authenticator is that it is still using passwords.
We know that passwords are not nearly as secure as a FIDO2-device like Trezor Model T.

Honestly. I’ve found some competent providers
. Was this a bribe what? Cause the fact blind eye is given to yubikeys protocols tells us this m company is a lazy and not respectful of clients or protecting them
-
Billy joe commented
Wow!!!
Inkdft Tutanota because I knew it supported yubikey surely and no?
Gals I didn’t go premium. Will keep people updated if I find a provider who take full care over their customers vulnerabilities

What I find fundamentally wrong with this email is that for years, users have been asking for this service with no response. Why should I continue to use and pay for this

Thierry commented
You should target the U2F protocol rather than one specific provider....
