Can I use multiple 2FA sources

So I am new to Bitwarden and 2fa. I have implemented 2fa authentication using Yubi keys and I don’t have any issues.
My question is I added another hardware vendor such as Hypersecure and implemented with no issue.

My problem or question is I thought I could use Yubi key if the Hypersecure key was not available, but I was not presented with that issue. Am I missing something or do I need to use the same hardware vendor

@bobn4907 Welcome to the forum!

When you set up your Yubikeys as Bitwarden 2FA, did you add them in the “YubiKey OTP Security Key” section or in the “FIDO2 WebAuthn” section? You should add them in the “FIDO2 WebAuthn” section:


got it; I need to all all keys to WebAuthn including Yubi keys. Correct?

Yes, if you want to use the Yubikeys as an alternative to the Hypersecure key.

thanks for the response

thanks - working now

I’m also new to Bitwarden. I came across this thread when searching for 2FA options. I have two brand new Yubikeys to set up on my account (Premium). One primary and the other as a backup. What is the difference in setting them up through the Yubikey OTP Security Key option and the FIDO2 WebAuthn option? I can see the last option is recommended on this thread but I don’t understand the difference.

Hey there, typically you will want to select WebAuthn, but when you click into each one you will see a list of platform restricts that can help you choose which is right for you.
