U2f with FIDO2 token nextcloud 26 php 8.2

🍱 Features & apps
1

Hello,
I just migrated to nextcloud 26 and php 8.2 without issues but the FIDO2 authentication stop working. I had several usb tokens configured and now that option of configuration just dissapeared and only can log with the one time passwords generated long ago. When I try to install a u2f app from the store I only see one webauth app that refuses instalation I think due to php version. The only possible option I see is a TOTP app but I would prefer the token option that (in my installation) has just dissapeared. Is it possible to configure again the usb tokens?

Thanks for your attention!

The U2F app was deprecated quite some time ago, and it was replaced by Two-Factor WebAuthn.

Yes, I knew that. The issue is that when I try to install the Two-Factor WebAuthn I get an error about gmp library. I am using php 8.2 and after install php8.2-gmp I keep on receiving the same error.

Maybe more installations are needed

Hmm, not sure then. I just installed the app on a test instance with PHP 8.2 and it worked right away with a Yubikey 5 NFC.

Here are the PHP packages / modules that I have installed / are enabled on that instance, maybe it is of any help.

Thank you for your help. This evening I will check it all.

Problem fixed, probably because a server reset I have done. Apparently after install GMP package a reset was needed.
