How To Send DMs On Twitter / X

Facebook gave me this message when I enetered my correct password:-

Choose a way to confirm that it's you
Your account has two-factor authentication switched on, which requires this extra login step.
Or, enter your login code
Enter the 6-digit code from the authentication app that you set up.

Now, I have performed all the steps you just mentioned in this video and for last one week I am daily repeating it with no positive result. One of Facebook FAQs suggested that i should check out my Facebook application installed on mobile but that is also asking the same authentication thing, CAN YOU HELP PLEASE?

Thanks

Is there a way to send an auto "Thank you for following" message to new followers?

Do you have to be subscribed

The person I want to dm is not showing up when I search the name in order to select and write directly to him. Please help.
