Login dialog on software app [duplicate]

Question

I´m building a dialogue for a software application.

The main purpose of the dialogue is to make it easier for new users to create a new account. They need this account to use the software. So, old users are going to see this too but they already have an account.

So focusing on the new users this is the process:

They want to login and a new window appears. Like this:

They have to put their email first, then if they don´t have an account they select the "No, I´m new to Yalala, I need to create an account". When they select that choice, the other choice (YES! I ALREADY...) puts in grey (like disabled) and the button of "continue" change to "create account" like in this:

Then we show a new dialogue saying that the account has been created and that we have sent them an email to active it.

Is the dialogue too complicated? Is it too unfamiliar?

Answer 1

Scenario 1:
Just wanted to confirm if you are showing one more dialogue to confirm about account creation. Because, if you are showing up one more dialogue on top when there is already one dialogue already opened, it might not look good UX practice.

Scenario 2:
When user click on 'Create Account', the dialogue box closes and new dialogue box opens. In this case, also, it does not looks proper to me as user may not be able to understand what is happening on screen. He is shown up with second immediate dialogue after first dialogue.

In both cases, I would recommend that you should display the success message in that dialogue itself rather than leaving user roam around clicking on these 2 dialogues. I hope you find this useful.

Answer 2

From another answer on ux.stackexchange,

Something like this would be better.

Also, Amazon does the same thing you suggested, but I'm not a fan of it.
