7 years later.... would be great to see it

WebAuthn

+1 for me !

I'd love to see U2F supported!

This should be quite easy! FIDO2 ;-)

This is why plesk is secondary to WHM... it's been SIX years for this feature that should've been included in the next update. Seriously, it's not hard, and its the year 2020. U2F authentication is STANDARD, countless services use it. There's no excuse at this point other than laziness or incompetence.

WebAuthn is the future standard! Need it really urgent

Please implement WebAuthn support and merge with respective thread https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/38640655-webauthn-two-factor-authentication-at-the-webinter

For starters, see https://www.murawski.ch/2018/06/plesk-mit-yubikey-otp-absichern/

2020 calling. Still no Yubikey?

U2F and the ability to add multiple tokens (Backup-Token)

I also agree, please merge this feature suggestion with the WebAuthn one.

Agreed.... Webauthn would now be the best way forward at this point in time.

general u2f/webauthn would be much more appreciated.
merge with https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/38640655-webauthn-two-factor-authentication-at-the-webinter ?

I created a new feature suggestion for the implementation of WebAuthn which is compatible with Yubikeys: https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/38640655-webauthn-two-factor-authentication-at-the-webinter

To Enable YubiKey (2FA) and our company (Sol distributor in Asia, Africa & CIS) will create YubiKey with laser engraved Plesk Logo

there is already a php class for yubikey availalble. But the documentation for plesk extensions is that bad, that I want do that.

I can only request it too...

We have a YubiKey Plugin that we developed for internal usage, we might release it soon. Stay tuned. :)

With Clef announcing a cease of operations, now might be a good time to revisit alternative 2FA options.

Yubico is indeed a token provider. The yubikey OTP is a service they provide on most of their products, they also support U2F on most (if not all) of their new keys.

The biggest issue with U2F at this time is browser support. At this time only Chrome and Opera supports U2F natively. Firefox has the ability to support U2F through an excellent third-party plugin. There is no support for Safari and IE/Edge.

If Plesk supports yubikey AND U2F then it would offer the best of both schemes, open standard authentication through U2F, and cross-browser support for people who can't/won't switch browsers.

i would like to see Yubikey and U2F implemented with plesk onyx as a part of a new security section
