Amazing onboarding UX makes for a successful product: Wix requires you to type your email twice when signing up, but disallows copy-pasting. Also requires you to type a password (with all those letters and numbers and whatnot) twice. It doesn't allow copying from a password manager.

Sometimes you don’t get the full picture as a user and there are other reasons for doing things a certain way. Not defending Wix but their customer support inquiries could have influenced the onboarding process as you see it.

Amazing how prevalent this anitpattern is.
How many wix users
Know what password manager is?
A successful product is usually
`functions * UX * marketing`
So features compensate a bad UX, and also a lot of visibility helps.
Then it is worth noting that some bad UXs can be intentional: they are planned to cut off users that are not enough tech savvy and could be a great cost in support if they generate bad feedbacks.
Btw, never used Wix, I cannot help :)
