Extends BE-login with email code verification
This extension adds a simple two-factor authentication via email to the backend login. For this purpose, an additional mandatory field for a one-time login-code is added to the backend login screen. This code can be requested by e-mail after entering the account name. The e-mail is sent to the e-mail address registered with the backend user's account.
If the environment variable is set to "Development", the generated code will always be "12345".
Therefore, it must be ensured that the environment variable is set correctly on the production-environment and that the e-mail dispatch is configured correctly.
