Working with Two-Factor-Authentication
Two Factor Authentication or 2FA can be used in order to increase the security of your account.
Enabling 2FA

OTP-Auth
OTP Auth generates a one time password in order to verify that the user can access the account (see here https://en.wikipedia.org/wiki/One-time_password ). Once enabled, the system will show you a key and/or a QR-code. You can use apps like Google Authenticator (https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2&hl=de&gl=US) or similar to generate these one time passwords.
