Hi, I lost access to my Authenticator app, and wikitech impossibly requires a code in order to disable 2FA, with no alternative methods provided.
One improvement would be to expand the form help text, and suggest that scratch codes e.g. "XXXX YYYY ZZZZ AAAA" can be pasted in place of device codes, in case of a lost device.
Update
I found my scratch codes, so all is good for me personally. Turning this task into feedback.
