Why use two-factor authentication?
Two-Factor Authentication (2FA) adds an extra level of security to your account. Besides your log-in credentials you are using an additional second factor in form of a one-time password. To receive this code you need an authentication app like Authy, 1Password, FreeOTP or Google Authenticator.
Before you can log into your account you will need to enter the generated password. This helps protect your account and data from abuse in case someone gains access to your login credentials.
How to Enable 2FA ?
Go to 'Settings' under 'Account' section in left-hand menu, scroll down to 'Two-factor authentication' Section.
Click on 'Enable 2FA' and you will be redirected to a page showing a QR-code.
Scan the QR-code with your phone.
Follow the instructions of your authentication app.
Make sure you have one of the aforementioned authentication apps installed on your phone.
Enter the displayed authentication code in the 'Enable Two-Factor Authentication' window and click on 'Submit'.
You will see one-time codes (backup codes). Click on 'Copy' or 'Download file' to save them. Then, click on 'Close'.
How to Disable 2FA ?
If you want to disable the 2FA, click on 'Disable 2FA' in the 'Two-factor authentication' section.
Confirm this move by clicking on the 'Disable 2FA' button again. To get redirected to the dashboard, click on 'Finish'.
