We highly recommend enabling two-factor authentication right after signing up.
In this article, we'll show you step-by-step how to enable 2FA as well as discuss possible issues.
- Log in to your account
- Open "Security & Settings" page
- Click on "Enable 2FA" button
- Follow the instructions therein:
- download Google Authenticator app (or any other app for this purpose, for example, Authy)
- log in to the app and click on "add new account/+" button
- point your phone camera at QR on the page
- enter 2FA code from the app
As soon as the code is added, the system will verify it and if everything is done correctly, 2FA will be enabled on your account.
2FA common issues
The 2fa is a black box service. There is not much that can be done about it. We don't control the reaction to the code that you are entering. You are entering the code, it is getting sent to the 2fa service and compared with the factual code on the server (in the case of Google authentication - Google servers).
The common reason why when you're entering the code, you see the error "invalid code" is you are entering an incorrect code, or you are entering a code not timely.
If Google/Authy 2FA code is not accepted:
Check if the time on your device and on the Google Authenticator app is synced. On the device, check General settings/Date & Time/Set Automatically. In the Google Authenticator app go to Main menu/tap More/Settings/Time correction for codes/Sync now. (See the alternative solutions here).
Please be advised. If for some reason you lost access to your smartphone and can't pass 2FA, you need to disable 2FA. Please send your request for that to email@example.com from the email you used to register an account at hexn.io
