Version 0.4.7

when registering a yubi key in profile I get:

PHP Error: Undefined index: hook_suffix
\wp-admin\includes\class-wp-screen.php on line 229

Thanks for reporting the issue @kkmuffme!

Looks like it is happening here:

https://github.com/georgestephanis/two-factor/blob/ab8d6510a17606b200d1e44a603c13b5014bac52/providers/class.two-factor-fido-u2f-admin.php#L313

Is that the first time you're registering the key? Are there any other keys current associated with the account?

[kkmuffme]

No the key was registered before. But I deleted the key (by clicking on "Delete")
Then later again registered the key again.

Yes, there were other keys associated before, but I also deleted them before adding the current one.

Any plans to fix this?

U2F is deprecated and no longer works in Chrome, so the provider is being removed in #439 . Given that, there's probably no reason to keep this open anymore.
