I logged in with login/passwd pair, and the portal started to beg importunately 2FA setup. All hyperlinks(including "Sign out" => Oooops, HTTP 404) turned to be broken, since any action leads to 2FA begging page again. The portal itself turned into an absolutely unusable crapware with only 2FA begging page. The page itself has bugs making it hard to use.
So:
- Logging out must work independently of 2fa state. 2fa is absolutely NOT REQUIRED for such operations.
- "Register with 2fa app" must provide detailed failure report, not only change the 2fa key.
- The "X" button in the "The global settings require you to enable..." info box must close this box.
