Facebook is problem with security keys,

As a title, we can not use security key for login Facebook on EDGE. 

[#2]

What type of key are you using?

[#3]

Thank you for answer. Actually, this happened long time ago. As you known, edge is using edg in UA string. But when I change Ua string to edge then it is working fine with Facebook login and also prompt Security Key when I login. But with edg UA string, it is opposite.

[#4]

What about if you remove the Edg/Edge token entirely?

[#5]

Sorry, what do you mean?
You mean If I delete edg in UA string? --> I use chrome UA string instead of classical UA string of EDGE then prompt for Security key appear normally./.

That makes sense, I'm sure they're not sending the right page if they think we're Edge Classic. As long as you can get it to work, that's what matters!

Hey@letuanvn ,

 If you're experiencing issues using a security key for Facebook login on Microsoft Edge, it might be due to the browser's user agent (UA) string. Edge uses "edg" in its UA string, which may not be recognized by Facebook for security key prompts. Changing the UA string to "edge" allows the security key prompt to work correctly. Consider modifying the UA string temporarily to "edge" to resolve this issue until Facebook or Edge updates their compatibility.
