Unfortunately, there is no official document said that security key authentication is supported in Teams for Linux. You could find the evidence from this picture:

2022-04-15T09:48:19.61+00:00 Do you mean the security key authentication could only be used in Teams web client?

In my case, I suspect because other authentication methods are still registered for my account, if I wait (about 5 mins or so) until the dialog box times out I can eventually re-authenticate using another method. But it's rather tedious, and in any case doesn't help if there are no other authentication methods registered for the account.

Mohammed Hamed 165 Reputation points2026-10-27T09:52:31.34+00:00 Currently, security key authentication is not supported in Teams for Linux. This is due to the lack of native FIDO2 authenticator support in the Electron/Chromium environment on Linux. As a result, users may experience authentication issues when attempting to sign in to Teams using a security key.
