There might be any number of scenarios where you could have lost your 2FA private key.
Please email firstname.lastname@example.org to pull in a request to disable 2FA.
Once Support has received your request, we will disable your 2FA.
To reactivate your 2FA,
1) Go to COSS.io and log in to your account.
2) Select "Security" and go to "Two Factor Authentication"
3) Activate 2FA
4) Scan your 2FA code. Follow the instructions on the screen
5) A private key will be displayed on the screen.
Note down your private key, or take a printscreen of this screen. Save it somewhere else. Do NOT use your phone to save this screenshot, since this key or QR code is needed to restore your QR code if you lose your phone.
Enter the code shown on your Google Authenticator app and click on “CONFIRM”.
That will reactivate your 2FA.
