Registration: twice password and Phone Number

how can i have twice passowrds fields in registration form and check that both are identical?

i also ask for the phone and put it as an Integer Numer and the field has two arrows on the right(above and below. ow can i change this behaviour?

I don't recommend doing that. The password field now includes a show button to show them the plaintext password if they need to confirm. Making them type it twice is bad UX. Anyway if you still want this edit the password field and enable it.

You can't, that's how a number field works. Use a text field with custom validation rule if you don't want that.

How can i enable two passwords and the verification that both passowrd are identical? all the pages have both password fields and i want to have it.

Edit your password field in CB > Field Management and enable verify password under its validation rules.
