Authenticator install was a bad idea

I can’t log in now. E-mail & password is ok. I keep going around in circles. Won’t let me in.
(I should have known to stay away from it)

brooo its even worse if you lose your phone you are screwed to remove phone number you need sms from your phone … or authentificator and likewise you want to remove authentificator it asks for sms or request from authentificator there must be someone with brain damage who did this … it makes 0 sense…
