I have been using TinyCam Pro with an android TV box for a long time. This morning I tried to load TCP on another android TV box and it asked for 2FA code. But I didn’t receive any SMS code (2FA default to SMS). Then I tried email, no code. I tried google authenticator but the code didn’t work.
Unfortunately the TCP was logout from the first android TV box and couldn’t log back in with code from google authenticator. I have to turn off 2FA.
I really want to turn 2FA back on while still being able to use TCP on my android TV box to view 4 cams in landscape mode. Using Wyze app will show only one cam in landscape at a time.
@alexey.vasilyev Any idea ?
Thanks!
There was another user who also had this issue from an Alexa Fire TV Stick 4K that had TCP side loaded. It might be a compatibility issue with the Wyze 2FA not accepting credentials from those OS platforms. 
Received SMS 2FA code in the past when logging in TCP but not this morning. All Wyze apps and TCPs were logged out when I switched 2FA default methods. Received SMS 2FA code when logging into Wyze app, but not TCP.
I would ask in the Tinycam Subreddit where the cofounder Alexey Vasilyev lurks:

As an added bonus, the TinyCam cofounder was also hired by Wyze in October 2020 as a Senior Software Engineer. So he’s the man to ask, and that’s the place to ask. If anyone can resolve this for you, it’s him,
It’d be great to hear a follow-up from you on this since I’m sure others may have similar questions in the future.
Somehow 2FA worked for my 1st android tv box this evening after I turned 2FA back on. I got the SMS 2FA code which worked.
2FA for my 2nd android tv box also worked after I updated TCP.
Then spent quite a bit of time doing 2FA for my many fire tablets and phones.
