[atlas] Fwd: 2FA

L.S.

Oh well, I installed the Authenticator Chrome Extension (https://chromewebstore.google.com/detail/authenticator/bhghoamapcdpbohphigoooaddinpkbai) on my PC which could scan (nifty!) the QR code exported from Google Authenticator. All is fine now. Can use 2FA via Chrome on my PC.

Regards,

Ernst

Which I don’t have and is also not available on my profile page. Tried exporting it in Google Authenticator which gives a QR code, pointed WinAuth to the URL where I stored it. Didn’t work.
