Yubikey 5 NFC fails to validate

[fansari]

I bought a new Yubikey 5 NFC (firmware 5.4.3) and want to use it with LastPass (via USB).

OTP is enabled with slot 1 configured.

When I try to add it I always get the message:

"Something went wrong. At least one YubiKey token failed to validate."

I do the same procedure with an older Yubikey VIP (firmware 2.4.2) and it works without problem.

Tested with Fedora 35 Silverblue and ChromeOS . Same behaviour.

From what I read Yubikey 5 NFC should be compatible with LastPass.

I have tested new and old Yubikeys using this site:

https://demo.yubico.com/otp/verify

The old Yubikey can be validated, Yubikey 5 does not work.

What is this?

I found the issue. The Yubikey Manager failed to upload my OTP for some reason.

I now entered my data here:

Working!
