My yubikey 4 has been working fine as a U2F device on both GMail and GitHub.
I've now followed the instructions for loading my GPG key onto the yubikey, which worked fine
https://developers.yubico.com/PGP/Importing_keys.htmlI did execute this, as instructed:
ykpersonalize -m82
However, I've noticed that my yubikey is no longer working for GMail login.
I think I've followed all the instructions correctly. GPG signing is working fine, with the yubikey. Is there some way I've overwritten the slot used for U2F?
Many thanks for creating this great product.
Regards,
Malcolm
