Authenticator app - 2FA, MFA

The front end information of this app does not have enough information. It is very hard to follow because I am given no backward and forward options to reread any thing - this app blindly wants me to agree to what is offered and there are no other options This is the same thing the bully does on the playground There needs to be more informative information at the beginning of this app process please - I have attempted to complete this phone app and the Facebook and requirements to completion for hours this afternoon and now again hours at night and I am sure I have not succeeded Very very discouraging
