I found 2 incorrect behaviors in the work of SCLogin:
1) if 2-FA is enabled for my account, and I log in through SCLogin, then this module asks me for a TOTP code (2-FA code), I enter the code and then I'm redirected to the website page, where I need to enter the TOTP (2-FA) code again.
2) if I have not enabled 2-FA for my account, then after entering the login and password, the SCLogin module requires me to enter the TOTP code (but I have not enabled 2-FA for the account).
if I log in through the default Joomla module, then there is no such problem.
Joomla 5.1.4, JFBConnect v9.1.76, SCLogin v9.1.77
