Betfair 2 step authentication 2021

Hi, i've just seen a similar post, but it's very old (2014)

https://community.welldonesoft.com/marketfeeder-general-discussion/betfair-2-steps-authentication/msg29740/#msg29740

Today I've tried to activate strong auth in betfair account but when try to login with MFP come out a "REQUIRE_STRONG_AUTH_CODE" error.
I've tried with "Secure browser" option, too, but without any luck.

There's some option to activate on MFP.s settings?

My MFP version is 8.9.2.3

The browser is the only option for 2fa.
What error do you get?

Any apparent error, just Betfair message "We are experiencing some technical issues and unable to proceed with your login. Please try again later."

Probably BetFair has some issues.
We've learned another way to use 2fa:
you should add your one-time code to your password and use "regular form".
For example your login is asdf, your password is qwerty and your 2fa software gave your code 1234.
Then you should enter asdf to login field and qwerty1234 to password field.
Let me know if doesn't help.
